Was wondering if anyone had a similar setup and could comment on the sound and drone increase. Basically the sound of just the gintani sport axle back is pretty much at my limit of how loud I want my exhaust to be but I do at the same time want to mod a bit. I can deal with a bit more sound but I don't want it to be to much. If anyone is in the tri state area with this setup, any chance I could check it out? Thanks!
Also: what exactly would a tune violate for warranty?
