Re: looking into a chambered exhaust. What a the pros and cons?
I used chambered exhaust in my old 72 vette. ZZ4 crate engine, M20 4spd, Flowtech headers into 2 1/2 (undercar) chambered exhaust. I have read that it is more restrictive than other exhaust systems, but not sure how much hp you would actually lose. My car dyno'd 262 rwhp. Other vettes with the same running gear but with mufflers dyno'd about the same, 260rwhp-275rwhp. The vettes independent rear sucks up more power than just spinning a 10 bolt straight axle. I don't know what a 67-69 Camaro with that running gear would dyno at. Could search it. Anyhow, back to the sound. You either love it or hate it. Its Snap, Crackle, Pop meets a Rip Saw! I got many compliments on the exhaust sound. Open it up under a bridge or tunnel and you swore you at Daytona. The higher you rev it, the better the sound. The vettes fiberglass tub of a body does strange things to vibrations/sounds. Amplifies them. Personally, I like the distinct, rowdy sound. Mellow and soothing, ITS NOT. Ride in a buddys car first. It sounds different sitting in it than it does standing beside/behind it.
