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


The extended tail pipe is the defining feature of the MPI Automotive MKGW0012: this 3in cat-back carries a centre muffler and runs the tailpipe further back to exit past the rear of the ute. It's listed to fit the GWM Cannon Alpha 2.0L turbo-petrol hybrid from 2025-on.
An extended tailpipe routes the exit further rearward so gases vent clear of the tray and rear bar rather than dumping early under the vehicle. On a working ute that keeps fumes away from the load area and presents a finished exit at the back. It's the longer-routed sibling in this cat-back family, pairing that extended run with a centre muffler to keep the note settled.
Sitting behind the catalytic converter, a cat-back swaps the rear section of pipe and muffler without touching the factory emissions gear. The 3in bore suits the Cannon Alpha's 2.0L turbo-petrol hybrid driveline, giving a freer path than the standard exhaust while the centre muffler absorbs the harsher tones.
Because the MKGW0012 is a cat-back, it leaves the catalytic converter and its sensors exactly where the factory put them — the emissions hardware that matters for registration stays in place. Confirm the build and any state requirements with the workshop before fitting.
