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

I don't know much about the differences - when I said I know less than most on the boards, I was meaning exactly that...

Cliff [Dynomite] has one method step-by-step for uploading snappics here. You can practice a few carshots upload before the hardware gets here... Learning stuff like that has application in how some of the Z diagnostic stuff works too - promise.

Work shots are good in MANY ways - it forces you to take your time (always good), gives you more time to see where stuff is, good for re-assembly reference, feedback from others, if you ever sell, you got photo-doc'ed proof, you 'learn' the stuff better (I will NEVER forget steps involved in the Top End Resto thread ('til tomorrow anyway )

Tom,

where did you find them?? I have flowmaster force II system and they are discontinued so I thought. Are they making them on a custom order method or did you just get lucky and find an old set somewhere?

This what is inside of your stock mufflers. Just in case you or anybody else was wondering. 2.75" shrinks down to 2.25" at the outlet. No wonder muffler swap gains good power improvement. I'm doing the same mod with my B&Bs.
