Exhaust
 

My flowmasters on my 05GT sound like they are comming apart inside since I put the offroad H-pipe on. They have developed a nasty rattle that is progressively getting worse. I have adjusted and readjusted everything on the bottom of the car and got all the nocks and rattles out now it's down to the mufflers. Anyone know of another muffler that sounds good and is not alot louder than the flowmasters, and aint outragiously expensive?

MAC Flowpaths are pretty similar to Flowmasters. Maybe a bit louder, but less interior drone I think.

I think that's a common problem with the flows, if they are the older ones. I think I heard that they will warranty some of them. Might be worth checking on.
