Default 84 Exhaust ?

Have an 84, just put new mufflers (stock style) on it and the car shakes at about 1400-2000 rpm's. The cat-Conveter has been replaced by a chunk of pipe(still has tube for the emissions). The noise is more than I can stand. Is there a way to calm the resonanace down a bit. Add a cross over to the Y pipe or making it a true dual exhaust system?

Ron, Walker makes a rear Y-pipe with the crossover tube, I have it on my 84 and it helped out. Don't know about deleting the cat, car will be louder without the cat though. Have you visited the Cross Fire Vault? http://www.crossfire.homeip.net/
Lots of good info on Cross fire cars

Thanks for the reply. I think i will try the cross over. Did it really cut down on the noise levels in side the car?

I went with the power effects side pipes and could not be happier with the results. :D
