Anyone running a Hi-Flow Y pipe with a Borla cat-back system? Just wanted to know how it sounds. I had a sho-shop Y pipe on my SHO and it sounded like a Honda. I really donâ??t want anything that loud. From what I've read Borla seems to be the most mellow and just a little bit louder then stock. I donâ??t no if thatâ??s with the Y pipe though.
