Great set of mufflers!

The quality and sound are great, just as loud as I'd hoped they would be. They are loud and do cause interior resonance especially in an older Vette where the cabin is so tight but I love the way they sound. And as always a great experience from Jegs.

Excellent sounding

Great sounding on a dual cat back for my 2002 V6 Mustang. Heavy duty mufflers. I owned one before and lasted forever. Mine broke in after a few miles.
