Two mufflers, not one — the MPI Automotive MKHN0038 is a muffler-to-muffler cat-back for the 3.8L V6 Holden Commodore VN, VP and VR sedan. Spreading the silencing across two boxes gives a more settled note than a single-box or open setup.

Why two mufflers?

With a muffler at two points along the run, the MKHN0038 spreads the quietening front-to-back rather than loading it onto one rear box. On the VN–VR sedan with the 3.8L V6 that reads as a more even, settled note. It's the choice when you want the cat-back freer than factory but still civil rather than loud.

What does a cat-back cover?

Cat-back means everything from the catalytic converter back to the tail, leaving the engine's emissions hardware in place. The mufflers quieten by absorbing and reflecting sound inside their bodies. The bore isn't published by the supplier, so confirm the pipe size with the workshop. We can't quote a sound level — hearing a comparable fit is the honest test.
