Front Muffler.5L Petrol - With O2 S (M1351) fits selected vehicle applications.
Category: Mufflers and resonators


The Redback M1351 is a front muffler listed to fit the Toyota Landcruiser 80 Series 4.5L petrol with an O2 sensor. The front position is what sets it apart — it's the first silencer in the run, and it's built for the petrol 80 with oxygen-sensor provision.
A front muffler is the first silencer in the exhaust, sitting forward in the system and taking the earliest pass at the noise before the centre and rear sections. On the 80 Series the M1351 fills that front position on the 4.5L petrol. Replacing it is a common job when the leading silencer has rusted or split — and getting the right one keeps the rest of the run quiet and sealed.
This muffler is listed for the petrol 80 with an O2 sensor, so it's built to suit a system that carries oxygen-sensor provision. Matching the front section to that setup keeps the sensor placement and the gas path correct. As a chambered muffler it quietens by absorption and reflection and restores the standard note; the supplier publishes no sound figures and we quote none.
It's listed to fit the Toyota Landcruiser 80 Series 4.5L petrol with an O2 sensor. The 80 ran across petrol and diesel 4.2 and 4.5 variants, so confirm your exact engine and build with the workshop before ordering. We verify the listing against the actual truck rather than assume.
Oak Flats Muffler Men supplies and fits the M1351 across the Illawarra. A front muffler swap means working forward in the run — we check the hangers and the joints, mind the O2-sensor connection, and set the new muffler so it clears the chassis under suspension travel. We'll inspect the centre and rear sections on the hoist too.
