Exhaust repairs & mufflers in Surry Hills Fifty years of bending and welding exhausts

  • Authorised pink slip & eSafety check station

  • Japanese, Korean, European & Aussie makes

Signs your exhaust needs a look

Exhausts rarely fail all at once. They tell you first, if you know what to listen for.

  • It's louder than it used to be, or it's started blowing or popping
  • A rattle underneath over speed humps or at idle
  • Something scraping or hanging low
  • A smell of exhaust fumes inside the car
  • Rust holes in the muffler or pipes

A leaking exhaust isn't just noise. It can fail your pink slip, and fumes getting into the cabin are a genuine safety problem.

Exhaust repairs we do every day

Repaired rather than replaced wherever that makes sense, and always priced before we start.

  • Mufflers and resonators
  • Rusted or cracked pipes
  • Blown gaskets and flanges
  • Broken hangers and rubbers
  • Rattling heat shields
  • Tailpipes and tips
  • Too-loud exhausts quietened down
  • Full replacement systems

Custom exhausts, built here

Not a catalogue part ordered in and bolted on. A system measured, bent and welded for your car in our Surry Hills workshop.

Commodore and Falcon sedans, WRXs, Golf GTIs, 86s, Civics, Mustangs, and older classics whose original parts are long gone. Tell us the sound you're after and we'll tell you honestly what it'll sound like, and what it'll cost, before we build it.

Common questions

How much does an exhaust repair cost?

It depends what's gone. A broken hanger or a blown gasket is a quick job; a new muffler costs more; a full custom system more again. Ring us with the make, model and year and we'll give you a straight ballpark before you come in.

Can you fix my exhaust the same day?

Often, yes. We keep our own pipe and muffler stock, so a lot of repairs don't have to wait on parts. Ring ahead and we'll tell you.

Is a louder exhaust legal?

Up to a point. There's a legal noise limit, and a car that's too loud can get a defect notice. We'll build it to sound good and stay on the right side of the law, and we'll tell you honestly before we start.

Do you do exhausts for older and classic cars?

All the time. Older cars often need a system bent up from scratch because the original parts are long gone, and that's exactly what we do.
