Get the best sounding, most powerful exhaust for your GT4RS.  No compromises. 32hp gains at the wheels at 8000rpm and 37lbft at the wheels at 4500rpm. Shortest possible secondary length with our through axle wave pipes and 18" shorter V11 rear muffler.  More power and still great sound, get that great high pitched Flat 6 scream! V11 muffler uses cutting edge 3d printed 347SS printed internals that would be impossible to fabricate.  This allows us to make more power, make it sound exactly how you'd like it to and keep it drone free!
