More smoke than usual from your tailpipe is a sign something needs to be checked.
A loud, rattling or leaking exhaust is more than an annoyance. It can affect your safety and emissions. Our muffler shop in Phoenix diagnoses it and repairs it right.
A sudden roar, a rattle over bumps, or a rotten-egg smell usually means a problem somewhere in your exhaust system. Beyond the noise, leaks can let harmful fumes in and hurt your fuel economy.
We inspect and repair everything from the manifold to the tailpipe: mufflers, catalytic converters, pipes and hangers. For exhaust system repair in Phoenix, AZ, we help keep your vehicle quiet, clean and emissions compliant.
We handle muffler repair, muffler replacement, catalytic converter replacement, O2 sensor replacement and exhaust leak repair in Phoenix for Dodge, Chevrolet, Toyota, Honda and Mazda vehicles, helping you pass Arizona emissions the first time.
“A quiet, sealed exhaust keeps you safe, saves fuel, and helps you pass emissions.
We make sure yours does all three.”

A louder engine usually means a problem further down the pipe. In this video, George walks through an exhaust system on the lift, from manifold to muffler. We check every section before a Phoenix driver fails emissions or breathes fumes in the cabin.
Before we quote anything, we inspect:
Exhaust leaks near the cabin are a carbon monoxide risk, not just a noise problem. Arizona emissions testing also catches a failing catalytic converter fast. We show you where the damage is and whether a clamp, an exhaust pipe repair, a catalytic converter repair or a full exhaust system repair is the right fix. Every exhaust repair we perform is backed by the NAPA AutoCare nationwide warranty.
These three symptoms point to three different problems:
A converter rarely fails on its own. Misfires overheat it, so the root cause may call for engine repair. Our diagnostic service finds the source, and a rich-running fuel system can damage a new converter if it is not fixed.
Failed emissions or hearing a new noise? Call or schedule online and we will inspect it, show you the parts, and quote in writing before we start. Larger jobs qualify for Synchrony financing.
Stay alert to these common warning signs – fix them early and save on bigger repairs.
If your car suddenly sounds louder than normal, it’s usually a leak or a bad muffler.
More smoke than usual from your tailpipe is a sign something needs to be checked.

Real feedback, real ratings – across the platforms that matter most.
A sudden increase in exhaust noise usually means a hole in the muffler or pipe, a broken hanger or flange, or a failed gasket. Loud exhaust is often the first sign of a leak, and exhaust repair in Phoenix is usually simple when caught early.
Yes, it can be. An exhaust leak can let carbon monoxide into the cabin, especially when you’re stopped or idling. A ticking noise at startup or a fume smell inside the car should be checked right away.
A rattle from under the car, a rotten-egg or sulfur smell, sluggish acceleration, a check engine light and a failed emissions test. A converter usually fails because of another problem, such as a misfire, so we find and fix that cause too.
An O2 sensor measures oxygen in the exhaust so the engine computer can adjust the fuel mixture. A failing sensor can lower fuel economy, trigger the check engine light and cause a failed Arizona emissions test.
Yes. Bring your test report to Pete Kelley’s Auto Service. We diagnose the cause, whether it’s an O2 sensor, an EVAP leak or a catalytic converter, complete the exhaust repair in Phoenix and prepare the car for a retest.
A loose clamp, a broken hanger or a small hole near a joint can often be fixed with a muffler repair. A rusted-through or internally broken muffler needs a muffler replacement. We put the car on the lift and show you which one it is.
