My impressions of the Hotshot Headers
The install was long and there was quite a bit of work involved. I am mechanically inclined, but would not have been able to tackle this install without my buddy who is a mechanic. Install took about 6 hours. To get to the bolts on the front manifold, the radiator has to be removed. To get to the bolts on the rear, the crossmember under the engine must be removed along with some heat shields and things.
We had the header portions installed and were putting on the down pipe portion. The pipe did not seem to line up AT ALL. I was quite upset. What we had to do was unbolt the front header and line up everything. We then bolted the down pipe to the headers and then tightened the front manifold. Then it fit quite well. The two holes underneath the car where the down pipe bolts into the car did not line up though. We just left the bolts out because the pipes are so light compared to the oem it seemed fine. Some instruction on the install would have been nice before hand.
On to the good stuff. The car is LOUD. You can see my mods below and the car absolutely screams. It is almost annoyingly loud, but I think I'll be able to get used to it. It is very intimidating.
The power increase is definitely there. I raced my buddy's STI and he couldn't believe how much faster my car was. My car pulls so hard now! I seriously recommend this modification. Dyno soon to follow.

Congrats. The headers do seem like they make nice power. Hopefully in the next few days we'll have several dynos to verify this.
What did you do with your rear o2 sensors?
BTW, you need to update your sig.

How much louder would you say it considering your setup? If your setup was kinda loud to begin with, then thats understandable, but if it was on the quiet side and made it loud as you say, then thats a whole other story. I am stock right now, but am considering the frankencar catback that almost sounds stock.
Oh yeah, would anyone recommend putting on headers with a stock exhaust? Would it not make sense since the stock exhaust would cancel out most of the gains from the headers?

-My car is stilll under warrantee. It has about 3,000 miles left. The dealer already told me if I put headers on, the powertrain warrantee would be void. Hopefully I don't have to switch back to stock for any dealership work.
-My car is loud like I said. This Altima video is a pretty good comparison. I'd say my exhaust is a little louder, but close. http://activetuning.homelinux.com/vi...dersgreddy.wmv (*right click and save as*)
-The O2 sensors were relocated to the rear.

I wouldn't see why not, though. A little gasket matching may be in order if it does not.

can anyone tell me privately how to do the ECU reset procedure ? Friend has a 02 Auto his wife has been driving since new, and I told him to reset the ECU. I heard there is some weird trick with opening doors or something, simple EREASE MEMORY in computer don't do anything ? Like with a scan tool ? cause I got one of those if anything.

With the windows up it seems to be as quiet as it was stock and slightly louder with the windows down.

Do you have stock exhaust other than the headers? Cause the other guys with the headers said they are very loud....
