MPI Automotive GWM Cannon Alpha Ute,2.0L Turbo Petrol Hybrid,2025 On,3in Catback Centre Muffler Extended Tail Pipe.
Category: Mufflers and resonators


This variant routes right to the back on an extended tail pipe: the MPI Automotive SSMKGW0012 is a 3in cat-back with a centre muffler and an extended tail pipe, listed to fit the GWM Cannon Alpha 2.0L turbo-petrol hybrid ute (2025-on). The longer tailpipe run is what marks it out from the diff-dump and rear-muffler builds.
Where a diff-dump exits early around the differential, the SSMKGW0012 carries the pipe through to an extended tailpipe at the rear of the Cannon Alpha. That gives a conventional rear exit and a longer run behind the centre muffler, which suits owners who want the gas exiting at the back of the tray rather than ahead of it. The centre muffler does the silencing in the middle, and the extended tail pipe sets the exit point at the rear.
A cat-back replaces the exhaust from behind the catalytic converter rearward, leaving the cat and front section in place and reworking everything from there back. The supplier lists this at a 3in bore, sized to the 2.0L turbo-petrol hybrid rather than a small engine. The centre muffler sits in the 3in run to keep the note in hand before the gas reaches the extended tailpipe.
It is listed to fit the GWM Cannon Alpha 2.0L turbo-petrol hybrid ute from 2025. The extended tail pipe changes where and how the system exits, so send the workshop your exact build and we will confirm the 3in routing and the tailpipe clearance before you order.
