unhappy with 3.5 exhaust
Hey all,
I just had a new exhuast installed on my 06 3.5L Monte, and I am not happy with the sound of it at all. I had a custom catback made from a local shop - 2.5" pipe, Magnaflow muffler, and Borla tip - because I didnt want to go with the Magnaflow dual exit. I talked to a rep at Magnaflow, and they said that a single exhaust would yield better results than a dual because of the fact that the 3.5 is only a single exit. Anyways, it sounds ok at idle, but at 2000rpm under normal acceleration, it has a really low vibrating sound to it. I'm going to take it in to the shop next week, and they said that they will put a bigger resonator on it, and I'm hoping that it will tame that sound down. Just a word of warning - make sure you know exactly what you want when changing your exhaust out. I will post an update when I get the new resonator put on. Anybody know anything about resonators? Do they restrict flow at all, or do they just change the sound?
Cheers

RE: unhappy with 3.5 exhaust
I found this on the Meineke web site:
Resonator
The muffler alone cannot always quiet all of the engine noise. Many exhaust systems also include a resonator which is like a mini muffler. They are usually straight pipes filled with sound muffling materials. The resonator can be either before of after the muffler in the exhaust system.

RE: unhappy with 3.5 exhaust
I was thinking of dual tips for my 3.5l. I wonder which would be better, taking the exhaust past the cat and going complete dual all the way back, or just replacing it with a dual outlet muffler.

After thinking about it, being called a straight pipe, the resonator is probably not that restrictive.

The temp fix was to crank the radio, but most women don't really like that when you're running smooth game.
Also I honestly didn't notice any power gain or loss with it in either place. I think it might actually help with the back pressure as well.
