My Hotshot header install experience (20 pictures, 4.38mb)
I recently bought some Hotshot headers. I decided to put them on yesterday. I know this sounds bad, but it took a total of 14 hours to put them on. The engine bay is very crowded for the installation of the rear exhaust manifold. Here are some pictures of the install.

The radiator fans and top coolant hose had to be removed. It allowed for more room to work on the front manifold.
One of the bolts of the heat shield was stripped. I decided to bend the shield and pull it off:
The stock front manifold. If you look closely, you can see that stripped bolt that was used to hold the heat shield on:

Nice job, so what does the Butt Dyno predict?

Nice pics.
Give it a few days. I swear my car felt faster everyday for about a week. You'll feel a power increase throughout the rpm range. How's the sound difference over the y pipe?

thats awsome... i will be going the with headers myself hopefully around my birthday in july. if u dont mind me asking what did the whole set up cost ya...r u pulling any codes, or do the sims take care of that? how loud is it compared to what u had on b4?
a lot, a lil, the way everyone wants our car to sound?
whyd u go with hotshot instead of cattaman?
sorry for all the ?'s

I'm happy to hear there were no fittment problems. I believe there were some on earlier production ones. Thanks for the pics...I'd really like to get some next spring. The install is a PITA, so 14 hours is not an excessively long time.

did you get them from sportcompactonly.com ? i plan on ordering a set from then within a month or so. where did you get the 02 sims?
thanks
thanks

It sounds like a beast at full throttle. I will try to post some vids of my car very soon. I went with Hotshot because if their good reputation. Fitment was good. I didn't want to spend more than $600 for some headers.

Nice pics, and good job.
It concerns me a little about the o2 sensors being under the engine cover. I assume they are still hooked up and the signal is simulated, but they are heated O2 sensors. They get kinda hot.

did you mean http://www.o2sensorsimulator.com/ the link you provided didnt work. 2 more quick q's. did you buy just 1 simulator and wire them up together, and what did you put in the 02 sensor location? a bung or something?

now time for a dyno. not just for the power increase but to figure out your a/f. i felt pretty big gains after my headers but found my a/f was running in the 11s after 4k rpms after the headers. with the y pipe that was on before, it was 13.5 across the board. it seems most 3.5s could use an afc or whichever piggyback to cure the a/f with them stock and after headers it seems to worsen.

The 24 points is unconfirmed at this point but i should know by friday when SR20DEN and I get together for a few other things. An afc will not negatively impact anything unless you tune it incorrectly. You could cause an over lean or rich condition which either cause detonation or reduced power. I am shooting for 13.5 to 14 a/f on the mustang dyno.
