it wont be a huge difference over stock, only slightly louder with a nice deep, mellow tone...i would pair it with an O/R prochamber, its not very loud, but the sound makes the panties drop
I guess I will have to do a search pretty soon (or just start the 1,256 thread on what exhaust to get) because after I get my car back with my new motor , Im going to be shopping for new exhaust to replace the sucky flowmasters I have now. I wish I could run a x-pipe but I cant because of my aode , oh well a new cat-back is what Im really after anyway. Post some vids of yours when you get it on.
