I recently bought an '04 s with Remus exhaust on it and the Cabin resonation while accelerating and cruising on the highway is horrible. Is there anyway to fix this? What exhaust system would still give a good sound without the resonation problems? I was looking at the Alta system anyone have opinions on it.

 

Wrong forum, my friend.

 

Where should I post it?

 

Your car is a 1st gen. On the resonance issue, take the car to a muffler shop that does custom work and add a resonator.

 

Ok sorry about posting in the wrong section. Thanks for the tip.
