Invidia N1 Exhaust Systems feature a cannon style muffler for maximum flow and minimised back pressure, resulting in significant mid to top end power gains. Invidia N1 exhaust systems feature a large diameter burned Titanium tip for an aggressive look.
*NOTE: Due to Australian vehicles having different down pipe lengths from MY01-MY07, MY01-MY05 WRX and MY01-04 STi will require modifications to ensure fitment to OEM down-pipe. Extension adaptor available separately to aid installation here.*
