MPI Automotive GWM Cannon Ute 2.0L TD 2020 - 2025, 3in Turbo Back With Muffler, With Cat.
Category: Mufflers and resonators


The quietest of the cat-retaining options, the MPI Automotive MKGW0005 runs a full chambered rear muffler on its 3in turbo-back for the 2.0L TD GWM Cannon ute (2020–2025), so it lifts flow over stock while keeping the note civil.
A chambered muffler quietens by reflecting and absorbing pulses inside a baffled box, so it's the calmest finish you can run on this 3in turbo-back. On the MKGW0005 it pairs the larger-bore breathing of a turbo-back upgrade with a muted tailpipe note — the pick for a Cannon owner who wants the flow benefit without a louder cabin or a drone on the highway.
Turbo-back means everything from the turbo outlet rearward is replaced, so the 3in bore runs the full length rather than just the tailpipe section. Starting at the turbo is where a small-capacity diesel like the Cannon's 2.0L has the most to gain from reduced restriction. The MKGW0005 keeps the catalytic converter, retaining the factory emissions hardware.
Because it keeps the catalytic converter, this system leaves the emissions equipment the Cannon left the factory with in place — the part that matters for road registration on a diesel ute. Confirm the exact build and any state requirements with the workshop before fitting; we don't claim a blanket approval on your behalf.
