The questions we hear before every booking.
Search by keyword — Mufflermen reception flags the answer.
Most direct-fit catbacks take 3-4 hours on the bay. Full custom stainless systems with TIG welds usually run 6-8 hours — we'll quote the exact time before you book.
installtimeEvery TIG weld done by a Mufflermen technician. If a weld cracks within 5 years, we re-weld it free of charge — even if you've changed cars, sold the system on, or driven 200,000 km.
warrantyNot unless you ask us to make it that way. Every Manta system we fit is signed off against ADR 83. We do a stationary noise reading before you collect the car.
noisecomplianceYes. Shellharbour City Council, NSW Maritime, and three civil contractors run their fleets through us. Quarterly audits, locked-key drop-offs, portal logging.
fleetcouncilWe will, but the weld warranty only applies to parts pulled from the Mufflermen cage upstairs. Bring your own and we'll quote install only.
partsAlmost always. We add a Helmholtz resonator or re-pack the muffler core to kill drone in the 1,800-2,200 rpm range. Quoted as a sub-2-hour job.
