best soundind exhaust
 

I just had MAC shorties, off-road pipe, and 2 1/2" FLOWPATH CAT BACK put on my 86 gt. To me they sound like glasspack mufflers. It could have something to do with the high compression of my motor or the 289 heads I'm using. I think that I'll change to anothe brand. My Dynomax SUPER TURBO MUFFLERS were quiet at idle, but had a nice tone when you were driving. This MAC system burbbles at idle. I don't think I like it.
