Cattman YPipe Installed......thoughts.....
so yeah, nyc hit 45 degrees tonite. and polo felt that was perfect temperature to install the cattman y. woke up at 9, went to work, till about 4, then treked on home (oh yeah, 1 hour traffic in the city, i hate parades)
so i finally get home around 6 and proceed to install the y pipe.
everything went semi-ok until i stripped my 14mm bit. which is what you NEED!!! to remove the cat bolts, and primary and secondary pipe bolts.
so i finally got the piece and proceeded to continue to proceed to remove the stock pipe. it's a PITA cause 1) it's cold, and 2) the yankee game was on. oh yeah, i'm also on gc's, so even on ramps, it was a tight fit.
putting the cattman pipe was a breeze, or so i thought. very few bolts compared to the stock pipe. the stock pipe has heat shield bolts, etc... so a lot more comes off than goes back on. in either case. the weight difference is unbelieveable. stock weights mid to high 20's where as the cattman weighed in at about 11 pounds.
now for the bad design, which i will talk to cattman about. if you look at this picture...look at the end of the secondary pipe, where the 3 bolt holes are....
now looking at that, look at ONE of the bolt holes. is it me or is the pipe BLOCKING THAT HOLE. yes, it is blocking it. so 2 of the nuts went on easily, #3 , i had to remove the pipe again and then squeeze the nut in JUST to get it on. you'd think i was done, but nope. the bolt that the secondary pipe goes through is rather long, and by being that long, i was unable to tighten the ypipe, everytime i tried to tighten the bolt (with a wrench because the blocking did NOT allow me to use a wratchet) the bolt would hit the pipe. and i was unable to continue. so what did i have to do, yes i had to dremel a bit off the bolt (about 1/4") and then i was able to tighten it. this was after realizing i don't have a dremel, and called my boy to give me a ride to my other friends house, who had a dreme, and then come back home to get back under the car. ok, now that time was about 11:30. i dremeled it off and tightened it....finally, it's installed.
w/out bad mouthing cattman, the rest of the pipe is a perfect fit, nothing was off and everything moutned perfectly. i just think that someone messed up in the bending. or maybe it's just has to be like htat. in either case, that was the one flaw in the design.
now the results:
turned the car on...it has definitely gotten louder, much louder not at all. at idle, again, the car is silent. revving it up, the greddy sounds manlier. i went down the block, and a nice rumble came out, again nothing too ricey but a notch louder than my greddy alone. went to my test block and did my run. overall feel is that power has increased throughout the entire powerband.i only say this cause my acceleration has now vastly increased. first gear does not last long at all, i'm changing into 2nd very quickly, and before i can be in shock, i'm already changing into third. definitely quicker acceleration. that seems to be the major impact on the whole "mod". i had my friend with me, he was my other opinion. his thought as i did a drive by are that the car is heard more, but it still sounds nice. a nice throaty rumble. nothing civic-ly. then he got in, i gave it some gas and took off. he also agreed that it seemed that my acceleration was so much faster and i climbed those rpm's way too fast
final thoughts...i have none....i was in it for 5 minutes....it's 12:45am, and i'm doing laundry and i have to be in the office early, so i won't mess with it anymore. i will do a few more runs tomorow nite throughout the xpressway (have to pick up my new custom grill) and i will come up with more results. other than the bolt flaw, everything else is given a thumbs up with performance a semi thumbs up until i can really give it some gas and also give the ecu some time to adjust. then again, maybe i'll have the TS ECU before it's even learned the ypipe =)
edit:
notice #1: i was in the lower range of 2nd gear and pressed the gas and the car jumped and started picking up immediately...that got a definite thumbs up and was extremely noticed.

Well, good to see that cattman actually makes a difference!
can't wait to see the grille!

so yeah, PITA and a success. kinda like when you do an intake and you realize that the hose will JUST not fit into that MAF adapter, but when it does, you're happy.

i'm taking friday off of work to setup my new suspension. john, jairo, if you wanna come over, i'll do your horns. you up for this? eric is gonna be there too, so he'll prolly do the horns while i'm taking apart my ground controls.
let's not stear off topic though. i emailed brian about this bolt issue, and awaiting his answer.
as for updates on the car, i haven't driven it yet...tonite 'll be driving throughout the city, into brooklyn, so i'll have a couple straight aways to test out my top speed. i know my top speeds in certain areas so if i reach them faster/easier, then that tells me this mod is showing a difference.

of all the bolts, the O2 surprisingly was the easiest to remove. a a little tug, but it loosened up rather quickly.
my only problem, which wasn't really a problem, is that the o2 sensor wires are connected to certain areas of the underbody by way of cable ties (or some variation of it.)
because of the wires being clipped, the o2 sensor wouldn't reach it's location. i cut the 2 clips and the sensor extended and reached the new ypipe's location. to be sure thati didn't get an error, i also disconnected the battery ground so as the ecu wouldn't realize that i unplugged something.

overall, i'm very happy with the quality of the product. this bolt thing just has me confused. i'm not mad at all, simply stumped as to why t his was overlooked. my assumption is that the 2k2 they tested it on had shorter bolts, or the builder turned the bolt so that i didn't bulge out that much. if that is the case, then it makes sense as to why it was hitting up against the pipe.
as far as worrying with dremeling. i wsn't scared at all....i did a nice clean cut, so i can just as easily remove the pipe and put it back on with no problems.
an added note...the stock ypipe...man that thing is twisted in so many different ways. i need to take a picture of it for comparison. if i can, i will also take some pictures of the bolt that was dremeled. this may calm some of you that are worried of dremeling. hell, bring it to me and i'll dremel it off. i'll even install the pipe for you......for $50...

Hmmmmm. I am about 65 miles north of NYC. It will be worth it for 50.00, are you serious about the offer.

i just did this last nite, and although it took me a total of 5 hours (it was dark, it was 45 degrees, and the yankee game was on man...hideki matsui owns you!!!!) now that i did it once, i can knock it out all over again and easily be able to do it in half the time. i'd say 2 hours, with most of the time saturating the bolts in lubricant to loosen them up.
you can entertain yourself, play with the gamecube in the car, watch a movie (i have a wide selection) or you can just watch me b!tch and moan if i hurt my finger
email me if you want.

putting the cattman pipe was a breeze, or so i thought. very few bolts compared to the stock pipe. the stock pipe has heat shield bolts, etc... so a lot more comes off than goes back on. in either case. the weight difference is unbelieveable. stock weights mid to high 20's where as the cattman weighed in at about 11 pounds.
now for the bad design, which i will talk to cattman about. if you look at this picture...look at the end of the secondary pipe, where the 3 bolt holes are....
now looking at that, look at ONE of the bolt holes. is it me or is the pipe BLOCKING THAT HOLE. yes, it is blocking it. so 2 of the nuts went on easily, #3 , i had to remove the pipe again and then squeeze the nut in JUST to get it on. you'd think i was done, but nope. the bolt that the secondary pipe goes through is rather long, and by being that long, i was unable to tighten the ypipe, everytime i tried to tighten the bolt (with a wrench because the blocking did NOT allow me to use a wratchet) the bolt would hit the pipe. and i was unable to continue. so what did i have to do, yes i had to dremel a bit off the bolt (about 1/4") and then i was able to tighten it. this was after realizing i don't have a dremel, and called my boy to give me a ride to my other friends house, who had a dreme, and then come back home to get back under the car. ok, now that time was about 11:30. i dremeled it off and tightened it....finally, it's installed.
w/out bad mouthing cattman, the rest of the pipe is a perfect fit, nothing was off and everything moutned perfectly. i just think that someone messed up in the bending. or maybe it's just has to be like htat. in either case, that was the one flaw in the design.
now the results:
turned the car on...it has definitely gotten louder, much louder not at all. at idle, again, the car is silent. revving it up, the greddy sounds manlier. i went down the block, and a nice rumble came out, again nothing too ricey but a notch louder than my greddy alone. went to my test block and did my run. overall feel is that power has increased throughout the entire powerband.i only say this cause my acceleration has now vastly increased. first gear does not last long at all, i'm changing into 2nd very quickly, and before i can be in shock, i'm already changing into third. definitely quicker acceleration. that seems to be the major impact on the whole "mod". i had my friend with me, he was my other opinion. his thought as i did a drive by are that the car is heard more, but it still sounds nice. a nice throaty rumble. nothing civic-ly. then he got in, i gave it some gas and took off. he also agreed that it seemed that my acceleration was so much faster and i climbed those rpm's way too fast
final thoughts...i have none....i was in it for 5 minutes....it's 12:45am, and i'm doing laundry and i have to be in the office early, so i won't mess with it anymore. i will do a few more runs tomorow nite throughout the xpressway (have to pick up my new custom grill) and i will come up with more results. other than the bolt flaw, everything else is given a thumbs up with performance a semi thumbs up until i can really give it some gas and also give the ecu some time to adjust. then again, maybe i'll have the TS ECU before it's even learned the ypipe =)
edit:
notice #1: i was in the lower range of 2nd gear and pressed the gas and the car jumped and started picking up immediately...that got a definite thumbs up and was extremely noticed.

Good writeup, and excellent input. Particularly glad to hear that you found the performance gains are so noticeable.
As far as the tight nut on the rear downpipe, that is an unavoidably tight spot but I think a relatively simple installation technique can be worked out. I'd like to discuss this with you on the phone, if you'd send me your # via email, I'll ring you up. Godspeed Performance in Detroit did the test fitment and dyno run on these and didn't mention any issue with that nut, so there might be some way to do this without cutting off threads.
The problem with that spot is that the bend is as tight as it can be made, so it actually enters the bottom of the flange at less than a perpendicular angle (the top opening of the flange is round, but the opening on the underneath is ellipsoidal). Since we can't raise the flange to create clearance, we would have to create a bend that goes down a bit before it can then come up into the flange at closer to 90 degrees (and thus create a bit more room). But, we can't do this because the bend would extend downwards enough to cause a clearance issue...
Since someone asked, I'll mention that pipes are not variable from one to another in terms of bolt-up points due to the extremely rigid manufacturing fixture they're made on, and all the tubing is CNC mandrel bent so there isn't much dimensional variation in the tubing either. We're just talking about millimeters, so we may be able to do something there. It would be useful to know exactly how much clearance is required to accomodate the unaltered bolt length. You had to trim so little off (and you might have gotten by with less), it may be that some pipes will have enough room and others would require adjusting the bolt length, and that we can adjust for this during fabrication and get a consistant result.
So you see the dilemma. We'll see about creating an installation advisory to make this seem simpler. In the meantime, hey, the part makes power, we know it can be installed without any guesswork, and most importantly...

02/03 Cattman Y-pipe Installation
This diagram and instruction set clarifies the adjustment Marco made to install his pipe, and briefly explains why this tight spot is a generally unavoidable design feature (the alternative causes a ground clearance issue, which no one wants). We'll be sending this out with every pipe, though some cars won't require doing anything -- its about half and half at this stage. As Marco noted, when you know what to expect, its a pretty minor issue.

Due to the very tight bend in the tubing under the rear triangular downpipe flange, the clearance under the rearmost bolt hole is very limited. This is somewhat unavoidable – creating more clearance forces the bend downwards, which would cause a ground clearance issue.
In some cases there may not be quite enough clearance for the pre-cat stud that extends down through this hole, i.e. as the pipe is tightened, the end of the bolt will extend further and further through the hole and possibly come into contact with the tubing underneath before the nut is fully tightened (the nut must be tight to create a complete seal between the pre-cat and y-pipe).
If this occurs, use a file or Dremel tool to take off as much as necessary (probably about 3mm or one-eighth inch) from the end of the bolt to create the required clearance so it can be fully tightened. Removing this small amount will not cause any problems if you need to restore the system to stock in the future.

no it is not.
and brian is right....this is more of an unavoidable problem. i may have come a bit strong....it may look like a big whoa but it really isn't much at all.....if anyone plans on having a shop do the install, they can VERY easy overcome this small issue.
and like i said before, i would be more than happy to help any NYer's or anyone willing to travel to me, if they are worried about shaving a little bit off the stud. took me 2 minutes to dremel the tip of it and it went on smoothly.
i must add though, it aint' free.....gotta make money somehow =)

PoLo & Brian Catts,Thanks. I misinterpeted the whole thing. I thought the flaw was a major issue. After re-reading the whole thread again this is a vey minor isssue. PoLo, Thanks for your review on the y-pipe. Brian I'll be giving your ordering service a call before the deadline(Oct.24th) to place an order for the 2k2-2k3 y-pipe. Thanks.
