    Great Sound but fitment issues 6 years ago
    4out of 5stars
    BettyWhiteS207
    Awesome and I mean 'Awesome' sound with stock headers but... make sure to get heavy duty hangers due to placement of the flange. Under heavy acceleration the flange can hit and break the inside CV boot. VERY LOUD Catless with tomei EL headers. If you need to sound like Ken Block heres your medicine. 4 Star for Quality and overall because of the placement of the flange.

        A:  The GReddy Supreme SP system is an absorption type muffler. Each muffler has a perforated center pipe (in most applications - straight through design) and packing material surrounding.
