GWM Cannon Alpha Ute,2.0L Turbo Petrol Hybrid,2025 On,3in Catback Centre & Extended Rear Muffler for selected vehicle applications.
Category: Mufflers and resonators


Twin muffling is what marks out the MPI Automotive MKGW0011: this 3in cat-back runs both a centre muffler and an extended rear muffler, so it's the quietest-biased option in the Cannon Alpha family. It's listed to fit the GWM Cannon Alpha 2.0L turbo-petrol hybrid from 2025-on.
Carrying two mufflers — one mid-system and an extended unit at the rear — gives the most sound absorption of the cat-back variants in this range. Each chamber takes another pass at the harsher frequencies, so the MKGW0011 leans toward a settled, refined note rather than a hard edge. For owners who want the freer-flowing 3in path without a loud cabin, that twin-muffler layout is the reason to choose it.
A cat-back changes the exhaust from behind the catalytic converter rearward. The 3in bore matches the Cannon Alpha's 2.0L turbo-petrol hybrid driveline, and because the run starts after the converter, the factory emissions hardware and its sensors stay untouched.
It's listed to fit the 2025-on GWM Cannon Alpha ute with the 2.0L turbo-petrol hybrid setup. Builds vary across the range, so pass your exact configuration to the workshop and we'll confirm both mufflers and the hanger points clear your vehicle before ordering.
