Built for the long-wheelbase Grange, the MPI Automotive SSMKHN0310 is a dual 2.5in extractor system listed to fit the HSV WL Grange V8. Twin 2.5in pipes run the length of the car, each carrying a hotdog resonator and muffler.

What does dual 2.5in mean on the Grange?

Dual means each cylinder bank runs its own 2.5in pipe rather than the banks collecting into one. On the long-wheelbase WL Grange that suits the wider, longer underbody. At 2.5in the bore keeps gas speed up for street response over a heavier car, with the extractors replacing the factory cast manifolds with mandrel-bent tube-and-merge runners.

Why the hotdog layout?

Each 2.5in side runs a hotdog resonator ahead of its muffler. The hotdog takes an early edge off the note in the mid-section, then the muffler finishes — a calmer exit than running straight to a single muffler. We publish no sound figure and won't quote one; the hotdog choice is the more reserved of the Grange builds.

Will it suit my HSV WL Grange?

It's listed to fit the HSV WL Grange V8. The long-wheelbase body and the dual 2.5in routing are the checks here, so confirm your exact car with us against the listing before ordering. Feed data is a starting point, not the final word.

What does fitting involve at our Illawarra workshop?

Oak Flats Muffler Men fits WL Grange systems in the Illawarra. We check the extractor flanges to your heads, route both 2.5in pipes the length of the car with proper clearance, hang the hotdog and muffler each side and seal the joints for heat cycling. RRP is listed at 4914.31 AUD; fitting is quoted once we've seen the car.

Stocked and fitted by Oak Flats Muffler Men, the Illawarra exhaust and 4x4 specialist in Oak Flats, NSW.
