Exhausting decisions
« on: April 08, 2006 - 01:36:19 PM »
 Getting ready to change my dual exhaust. I have added the rear valance with cut outs. I checked the part #s on the exhaust manifolds and the are the 68-69 HP ones, so I plan on having the header pipes bent locally. I don't want anything raddical and would like the noise level stock to moderate. Should I use Accurates' Rear mufflers and tail pipes with the resonators or with out resonators? I do have a pair of stock resonators. I don't want to have too much vibration inside the car at cruising speeds but want it to sound nice when romping on it! Any insight will be of great help.
Thanks ,383 SE

I would go without the resonators although you will have some noise inside at certain rpm's. With my experience on small blocks the noise is only bad between 1700-2100 rpm. I think the exhaust with the resonators makes the car to quiet.

I have the stock mufflers, H-pipe, without the resonators, behind a mild 440 with 1-7/8 headers. Good sound for cruising aroung.    Remember, e-body resonators are in front, mufflers are at the rear. Don't let anybody tell you different.

 I've decided to have the shop put in a short seperate piece where the resonators go so that if I decide to add them later, I can. 
Thanks for the replies!
