Redback Performance Centre Muffler Assembly.
Category: Mufflers and resonators


The Redback STR503 is a performance centre muffler assembly listed to fit the Toyota Landcruiser 105. Unlike a plain replacement silencer, it's an assembled centre section tuned toward freer flow for the 105-series wagon.
The STR503 is sold as a performance centre muffler assembly rather than a stock-style drop-in. A performance centre section is built to ease the restriction the factory silencer puts in the middle of the run, so gas moves through the 105's exhaust with less choke. It's an assembly — the muffler and its pipework as one mid-section — which makes the install a single, matched piece rather than several joints.
This is the centre run on the Landcruiser 105, between the front of the system and the rear silencer. Being a freer-flowing performance muffler it tends toward a fuller note than the standard part, though it's still a muffler doing the quietening by absorption and reflection rather than a straight-through. We have no sound data from the supplier, so we quote no figures — only the honest character of the type.
It's listed to fit the Toyota Landcruiser 105. The 105 ran across a few drivetrains, so confirm your exact build with the workshop so the centre assembly matches your truck. Listed-to-fit data is a guide we verify against the actual vehicle before ordering.
Oak Flats Muffler Men supplies and fits the STR503 across the Illawarra. As a centre assembly it goes in as one section — we remove the old centre run, check the hangers and the joints to the front and rear, and set it true so it clears the chassis and tailshaft under load. We'll inspect the surrounding pipework while the 105 is on the hoist.
