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


This is the diff-dump variant: the MPI Automotive SSMKGW0013 is a 3in cat-back with a centre muffler that exits as a diff-dump, listed to fit the GWM Cannon Alpha 2.0L turbo-petrol hybrid ute (2025-on). Instead of routing all the way to a rear tailpipe, it dumps ahead of the rear, which sets it apart from its siblings.
A diff-dump finishes the exhaust around the differential rather than running a pipe to a rear tailpipe. On the Cannon Alpha that makes for a shorter rear run and is the choice for owners who want the gas exiting ahead of the back of the tray — useful where rear clearance or a tow setup matters. The SSMKGW0013 pairs that exit with a centre muffler, so it keeps a chambered silencer in the middle of the system while ending in the diff-dump.
A cat-back replaces the exhaust from behind the catalytic converter rearward, so it leaves the cat and the front of the system alone and reworks everything from there back. The supplier lists this at a 3in bore, sized to suit the turbo-petrol hybrid 2.0L rather than a small naturally-aspirated engine. The centre muffler sits in that 3in run to control volume before the diff-dump exit.
It is listed to fit the GWM Cannon Alpha 2.0L turbo-petrol hybrid ute from 2025. Because the diff-dump changes where the system exits, send the workshop your exact build and we will confirm the 3in routing and the diff-dump clearance before you order.
