Powerhouse Amuse exhausts are the best in the world, but just a heads up for our stateside (USDM) guys, the rear muffler section will hit our EVAP canisters for sure. The guys at Bulletproof Automotive/370ztune (Amuse's exclusive worldwide distributor) found out the hard way with the non-USDM Amuse exhaust. Notice the bend on the right of the rear section; the USDM version curves less than the standard version in order to clear that dumb EVAP canister we have.
Just food for thought.
