Headers & exhaust

My current solution is headers, no cats, and an LT-4 stock exhaust from the collectors back. No resonance and sounds stock in the cabin, but somewhat louder outside. Without a dyno comparison I can't comment on HP loss but in real-world driving it doesn't seem that I lost much, if any, and it "feels" like I picked up a little torque. Again, without a dyno that doesn't really mean anything but I'm reasonably happy with the system ... for now.

George, this is exactly what I went through. Primarily Corsas over the years but just got tired of the Loud. I have headers, no cats and last year had Marc reinstall my stock '95 system from the headers back. The only difference is I had him add electric QTP cutouts and I installed a rocker switch hidden under the carpet on the right side of the console. The only issue is I had to sacrifice the spare tire carrier. On longer trips away from home I carry the spare in the back. I added small tips to direct the exhaust to the side. So far I like the setup a lot. It is stock quiet when I want and when open I can scare children and pets and set off car alarms. I normally run slightly open for a little rumble.--Bob
