    Rated 5 out of 5 by from Fantastic Sound I've used many of these in my fabrication. The quality Borla sound you're looking for is present in this model. The Stainless material is great although the casing material is a little thinner than I would prefer, so be carefull welding hangers directly to it. Other than than, two thumbs up. Side not.. do not cross flow.

    Rated 1 out of 5 by from Loud Drone Installed muffler on LS based 5.3 with Hooker cast manifolds, 2 1/2" dual in, and 2 1/2" dual out (no resonators or cats). Loud drone most of the time. Sounds good at idle. Sounds ok at wide open throttle. Overall too loud and the tone is not that I would call good either. Would not go this route again without resonators.

    Can this muffler be used as a transverse style like the 69 and Shelby mustangs if not do you offer transverse mufflers for the 68, 69, 70 shelbys.

    If you have the room it is only made for 1 side inlet and 1 side outlet.
