The MPI Automotive SSMKHN0131 finishes a 2.5in dual extractor system through a muffler and out a tailpipe, listed to fit the VY-VZ HSV V8 sedan. The single-muffler-then-tailpipe rear sits between a fully damped build and an open exit, giving the V8 a clear but liveable voice.

What does the muffler-and-tailpipe rear give you?

Rather than damping each bank with its own muffler, the SSMKHN0131 runs the 2.5in dual through a muffler and then exits at a tailpipe. That lets the V8 note carry more openly than a twin-muffler build while a single silencer still keeps it road-liveable. No sound figure is published, so this is a relative description of the layout, not a measured level.

What are extractors and what do they change?

Extractors, also called headers, swap the engine's cast exhaust manifolds for separate tubes that merge further down the system, aiming to ease back-pressure right where the gas leaves the cylinders. A dual layout keeps two pipes running rearward, which suits the V8's split cylinder banks, and the run finishes through the muffler and tailpipe. The honest trade-off with any extractor change is that it's a more involved fit than a bolt-on rear section, which is why this is supplied as a complete, matched system.

Will it suit my HSV sedan?

It's listed to fit the VY-VZ HSV V8 sedan. The 2.5in dual run is street-oriented sizing — paired pipes hold gas speed up for low-down and mid-range response on a road-driven car. HSV specifications differ across VY and VZ, so confirm your exact model and build with the workshop before ordering.

What does fitting involve at our Illawarra workshop?

Oak Flats Muffler Men fits HSV extractor systems in-house across the Illawarra. We confirm extractor access and clearances at the engine first, then route the twin 2.5in run through the muffler to the tailpipe exit. At an RRP of $4,596.08 it's a build-to-order item; send your VY-VZ HSV details and we'll confirm the fitment.

It's listed to fit the VY-VZ HSV V8 sedan. Confirm your exact HSV model and build with the workshop before ordering.
How is the back end configured?
A single muffler then a tailpipe on a dual 2.5in run — more open than a twin-muffler build, but still silenced.
