I haven't put it on a Dyno yet to compare but it seems pretty noticeable to me. They sound great but I'm just not moving. And if you are wondering I did update the tune with Steeda for the long tubes. Any ideas?
Mach Thunder all day. Sounds amazing and quality is great! You will not be disappointed. I have someone say that they love the way my car sounds at least once a week!
