Toyota Hilux N70 GGN 4.0L V6 2.5in Cat Back Exhaust, Centre Muffler, Rear Hotdog (SSMKTY0065) Fits TOYOTA.
Category: Mufflers and resonators


The MPI Automotive SSMKTY0065 is a 2.5in cat-back with a centre muffler and a rear hotdog, listed to fit the Toyota Hilux N70 GGN 4.0L V6 petrol. The petrol V6 application and the muffler-plus-hotdog pairing set it apart — a balanced cat-back tuned for the V6 rather than a diesel build.
This cat-back runs a centre muffler to chamber and absorb the bulk of the sound, then a rear hotdog — a straight-through resonator — to trim the remaining harshness while keeping flow up at the back. On the 4.0L petrol V6 that balance gives a cleaner note without the heavy quietening of a twin-muffler setup. It's a measured petrol cat-back rather than an open build.
A cat-back replaces the exhaust from the catalytic converter back, leaving the cat and the rest of the emissions hardware in place. At 2.5in it's sized for the 4.0L petrol V6 — a sensible bore for that engine rather than an oversized diesel pipe. The centre muffler and rear hotdog are spaced through the run to manage note and drone.
As a cat-back, the SSMKTY0065 leaves the catalytic converter and the factory emissions hardware ahead of it in place. The supplier doesn't publish a separate cat in this section because it's a cat-back, so confirm your full setup and any state requirements with the workshop before fitting.
Oak Flats Muffler Men fits cat-back systems like this in-house across the Illawarra. We check the 2.5in routing from the cat back, set the centre muffler, rear hotdog and hanger positions, and seal the joins. RRP is $1,372.62; bring the N70 in and we'll confirm the V6 fitment and how the result will sound before booking.
