I cant add any more than what I put on the nearby lengthy ex thread but I am a firm believer in X pipe setups along w resonators along side the rear springs in addition to dynomax muffs. Yes pri tube dia/length is important and the link states collector dia/length is also & I believe that any dia reduction from the header collector flange rearward (starting w collector reducers) costs power though the 1 guy said he went from 3" tailpipes to 2&1/2" & lost virtually nothing.

i agree with the use of an X-pipe to make that extra bit of power. but,with 450hp,honestly,a mild 440, 3" exhaust is complete and utter overkill. 2 1/2" is more than adequate,with dynomax ultraflows and round,canisiter style resonators at the rear,will offer a nice mellow,deep,yet non-johnny-law-dawg-attracting sound.

I used "Accurrate Exhaust" on my car [69' runner] with stock exhaust manifolds. I used their over the axle pipe instead of resonators, which it should have. The car is very quiet. No droning,vibrating, ect. I too wondered about performance loss at the time, but am very happy with results, looks, sounds, performance, ect. ![](/ubbthreads/images/graemlins/thumbs.gif) The car goes low 13's 1/4 mile @ 104 mph. My goals were not maximum performance, so I was [and still am] O.K. with leaving some perf. on the table. It is worth the driveability aspect of it for me As you already know, you will need to decide on looks, sound levels, performance goals, originality, ect. Happy decision making!! ![](/ubbthreads/images/graemlins/burnout.gif)

I have 4 mufflers, 3-1/2" system, incl x-pipe, over the axle, 2-1/4 TTI's into 4" collector. Room was an issue. Not sure of the sound yet, but hoping 4 x magnaflows will quiet it a little.. ![](/ubbthreads/images/graemlins/Twocents.gif)

BTW, on e-bodies the round cans behind the axle Are the mufflers, the resonator are the ones under the floor pan.
