The MPI Automotive SSMBM459MF-NOTIPS is a rear muffler for the Holden WK–WL and HSV Grange 6.0L V8, supplied in the no-tips configuration. The no-tips spec is the defining choice — a clean rear-muffler section without finishing tips, ready for the outlet treatment you want.

What does 'no tips' mean here?

This rear muffler is supplied without finishing tips at the tailpipe — that's what the NOTIPS designation marks. It's the choice for an owner who wants to fit their own tips, run a tipless outlet, or match an existing rear look rather than take the muffler's standard tip. The muffler itself is the rear quietening stage: a chambered, absorptive unit that softens overall volume and sets how loud the car finishes at the back. Leaving the tips off changes the finish, not the muffler's job.

What does the rear muffler do on the WK–WL Grange?

The rear muffler is the last quietening stage before the tailpipe on the Holden WK–WL and the HSV Grange 6.0L V8. A chambered muffler rounds off the harshness and decides the final volume at the back, working with whatever centre and front pipework the car already runs. This is the rear section specifically, so it's the targeted change for owners altering the final note rather than redoing the whole system. It's listed to fit the WK–WL and HSV Grange 6.0L V8; confirm your exact model with the workshop.

Is it road legal?

This is a rear-muffler section. It doesn't include or delete the catalytic converter, so the cat-delete off-road rules don't apply to this part. A rear-muffler change does alter how loud the car finishes, so confirm the in-service note and any state requirements with the workshop before fitting.

What does fitting involve at our Illawarra workshop?

Oak Flats Muffler Men fits Grange rear mufflers in-house across the Illawarra, hanging the rear, checking the outlet position and, since this is the no-tips version, helping you sort the tip or outlet finish you want. The SSMBM459MF-NOTIPS carries a published RRP of $1,170.79; send your build and we'll confirm fitment and book the bay.
