Has anyone installed the new GM H3 exhaust system yet ?? If so, any thoughts on it?? Touring or performance??
I have the SMA and have never been completely happy with the increased cabin noise and am thinking of going with another system and was thinking of the GM one.
Any thoughts would be much appreciated !
