yoo, at idle it rumbles identical to a 5.0, its beautiful. Yea it gets prety loud when you rev it. During the dyno runs, there was a guy that had just gotten there as I started my first pull, and the dude asked if I was boosted (because of the change of tone around 4500- when the IM really starts to flow), it really does sound like spoolup lol.
To the dyno n00bs, do not be concerned about my a/f during my cutout run. Remember its a cutout, so SOME of the fumes are still going through the regular catback, so it will READ leaner, just like an "exhuast leak" would.
Beware, ground clerance is of an issue here. I havent scrapped it on anything since its at about the same level as the SFCs, but I do go over speedbumps slower and sideways just as a precaution.

Just curious what were the SAE #'s? IBmyinboxdoesnthaveanydrfsinit
I don't like too much noise, in fact really none (at best MINIMAL) at all. With that said, I don't think I'll be doing this as of now . This is coming from a dude that is thinking about cams vs changing his muffler for probably the same amount of gain .

Seriously man (all of you contributors), I gotta hand it to you, you've really taken the time to prove/disprove certain myths/facts. Which only adds fuel to my flamethrower whenever we get a thinking otherwise w/o any proof. . .

Damn... I get stuck in Jamaica and come back to find everyone from South florida doin big things. I've been cookin up something in secret for a little while now too. It involves boost and an A33. Only problem is I just lost my job. So untill I get another one, cash saved up to continue the project is used for school and bills. I was expecting something to get in my way with my luck... lol
Time to hide for another month or so again...

- Im at work bro, I got enough time to post up the stuff and then i go do stuff around here, lol. I'll send em over when I get home. SAE #s are 250.56WHP/ 239.61WTQ.
- Noise is of no concern here. The only time it will get noisy is when you take off the cover plate. As long as that plate is on, and theres no exhaust leak (the paper gasket is useless caca, just lay a thick bead of cooper silicone around the mating surface, let it air dry for a few hrs, and THEN put it on, it will seal with no problem), wont be any louder than a test pipe.
- gtr_rider PROBABLY wont have his surprise ready for Xmas, thats me that has a surprise for then. Hopefully he wont be too far behind me (maybe for Reyes Magos Day? lolz)
- Werd man, gotta love $35 dyno Thursdays. Been there so many times they know me by my gov't name LOL)

Ok meng, so about the same gains right..... cams= 650 for debuloz, and ~1300+ for custom tomei depending on what you want...
or $35 shipped for cutout
better yet, COMBINE the two, o0o NOW you got something serious cooking there... and you get to keep your stock muffler

pretty huge gain from just the cutout. i guess my 3" catback might be of some use for NA after all...
I dunno what his catback/test pipe was like, maybe it was restrictive. I'm fairly certain my cutout didn't give much/if any gain over the Cattman 2.5" catback, based on track results. But that is on a 3.0 not a 3.5...

Previous= long tube headers, custom equal length ypipe, WSP test pipe and B-Pipe (has an 18" resonator on it, just to note), DynoMax 2.5" muffler
This is all mandrel-bent, so I wouldnt think of that setup being restrictive. Not much of a science after all in making a B-pipe for our cars, its only going to fit one way and they'll all need the same bends. Unless my muffler is restrictive? Meh, that muffler is getting replaced soon anyways, feel like being a ricer and changing it for something else
NMexMax........... stop making fun of my stock fuelcut! Lol. I told him to bounce it off redline every time cus the stock tach is useless in that range

Well, I have dyno results closed and open cutout back to back, and I got just as good gains, my catback is 2.5" with Dynoxmax superturbo 2.5" muffller, thats about it.
505max94SE- thanks! Maxboost925- you can still use the cutout, right after the turbo is where streetz has his. Closed and it runs it through the muffler and its the ULTIMATE sleeper. Open it up and.... Omg that spooling sound with rumbley idle FTW, lol. Meximax- Thank you! and check your PM NMexMax- ..... wow, after 5250 our graphs are basically identical! just mine is a bit higher. wow thats insane I finally found a way to match your power curves w/o messing with int cam timing, w00h00! If only I had extended revs to take advantage of it, lol... just think of the gains YOU would have with zee cutout
