I know, but nobody seems to know how magnapacks or bassani sound on n/a 4 valvs. haven't found any sound clips. chronic told be about the borlas and I have heard them on a termi, they sound badass. I'm still open to suggestion. I want a really deep throaty sound, my flows crackle and I hate that. I also don't want to set every car alarm off for 1/2 mi around. i live in a nice neighborhood with alot wealthy professionals. They complain about it already. Also I'm using an off road H pipe.
