I'm debating whether to save up for a new exhaust or just keep the one I have on the H3. I wanted to get some feedback from owners that have replaced their factory exhausts with any kind of performance exhausts.

I like how quiet it is now, but want the peformance boost. Have any of you out there noticed any considerable amount of noise increase on the highway due to an exhaust system upgrade, or does it only become loud when you hit the gas?

 

I notice my magnaflow all the time. It is deeper at idle and noiser at all speeds but then that is part of the reason I got it.

 

My little "modification" isn't too bad at HWY speeds. You CAN hear a little bit of drone from it but not much. Like Dave said, partly why I did it.

I can still talk on my bluetooth and it doesn't bother the other end of the call.
