Muffler & Exhaust Repair in Round Rock, TX
An exhaust that got loud overnight, a rattle over every expansion joint, a drone that builds the moment you merge onto I-35 — our Round Rock shop at 1001 Louis Henna Blvd finds the cause and fixes it for every make and model. Mufflers, resonators, pipes, hangers, gaskets, and catalytic converters, all with a written estimate before any work begins.
Why drivers choose us
Round Rock commuters live at highway speed on I-35, TX-130, and TX-45, where a small exhaust leak becomes a droning headache and can pull fumes toward the cabin. We inspect and smoke-test the full system instead of guessing, then quote the actual fix in writing. If custom-bent pipe makes more sense for your repair than a direct-fit part, we say so — and we explain why before you commit.
Convenient for Round Rock drivers
Easy access off I-35 and Louis Henna Blvd for Forest Creek, Brushy Creek, Behrens Ranch, Teravista, and Paloma Lake — Georgetown drivers are about 12 minutes down I-35. Most exhaust repairs finish the same day, with a free shuttle within 10 miles. Open Monday–Friday, 8 a.m. to 6 p.m.

Exhaust & Muffler Repair FAQs
Why is my exhaust suddenly so loud?
Usually one of four things: a rusted-through muffler or pipe section, a blown flange gasket, a cracked exhaust manifold, or — if it happened overnight in a parking lot — a stolen catalytic converter. We put your car on the lift, show you the failed part, and put the fix in writing before touching anything. If diagnosis takes shop time, the diagnostic fee is credited toward the repair.
How much does muffler repair cost in Austin?
It depends on what failed and how it's fixed: a leaking gasket or broken hanger is a much smaller job than a rusted-out muffler, a direct-fit part installs faster than custom-bent pipe, and some vehicles bury their exhaust components deeper than others. We diagnose first, then hand you a written quote before any work begins — and every repair is backed by our 12-month / 12,000-mile warranty on parts and labor.
My catalytic converter was stolen. Can you repair it?
Yes — converter theft repair is routine work at both our shops. We assess the cut pipe, install a converter that meets emissions requirements for your vehicle, and document the damage with photos and a written estimate for your insurance claim. Don't drive on it long: Travis and Williamson County vehicles still need an annual emissions test, and a missing converter is an automatic fail.
Will an exhaust leak make me fail the Texas emissions test?
It can. Texas ended annual safety inspections on January 1, 2025 (House Bill 3297), but vehicles registered in Travis and Williamson County still need an annual emissions test to renew registration. A leak ahead of the oxygen sensors can skew readings and trigger the check engine light — an automatic fail. We perform emissions testing at both shops, so we can fix the leak, verify it, and re-test in one visit.
