Twin Falls' Trusted Auto & Muffler Shop Since 1983
Bill's Automotive & Muffler has served Twin Falls drivers from Main Avenue since 1983. Over four decades of honest, reliable repair built on a foundation of trust locals have shaped with us one vehicle at a time. We started as a muffler and exhaust shop and grew into a full-service repair facility, but that original specialty is still part of what sets us apart. When you need exhaust work done right the first time, this is where the people of the Magic Valley have come for decades.
Today we handle everything from brake service and diagnostics to engine repair and routine maintenance, alongside the muffler and exhaust expertise we've built our name on. Our ASE-certified technicians give you clear answers, and our thorough inspections on every vehicle let you see exactly what's going on. That's what we mean by raising the standard: no pressure, no runaround, no surprises.
As a NAPA AutoCare Center, every qualifying repair comes with a 24-month, 24,000-mile nationwide warranty honored at over 14,000 locations. We serve Twin Falls, Jerome, Kimberly, Buhl, Filer, Hansen, and the broader Magic Valley. If you're looking for a Twin Falls auto shop with the experience to diagnose accurately and the integrity to recommend only what your vehicle actually needs, we'd like to earn your trust.

We Don't Guess. We Inspect.
All 54 Points
Every vehicle that comes through our doors gets a documented, photo-backed inspection of all major systems. You get a written report of exactly what we found.
Our 54-point inspection covers nine systems: vehicle documentation with photos, wipers and windshield, lighting, heating and cooling, engine and underhood, tires and wheels, brakes, exhaust and underbody, and suspension and steering. Every point is checked, every finding is documented, and the report is yours to keep.
We road test before we inspect. We measure brake pad thickness and tire tread depth at all four corners individually. We photograph the underhood, the exterior, and the dashboard before we start. This is what a real inspection looks like, and it's included whenever you want it.
Every Repair Backed by a Nationwide Warranty
Bill's Automotive & Muffler is a certified NAPA AutoCare Center, which means every qualifying repair comes with a 24-month, 24,000-mile warranty honored at more than 14,000 NAPA AutoCare locations across the United States. If a covered repair issue surfaces while you're traveling anywhere in the country, a NAPA shop takes care of it.
Same protection you'd get at a dealership. Without dealership prices.

Frequently Asked questions
-
Walk-ins are welcome. For oil changes and quick services, just come by. If you're coming in for a diagnostic, an estimate on a specific repair, or a larger job, calling ahead helps us make sure we have the right technician available when you arrive.
-
Yes — domestic and import, cars, trucks, and SUVs of all makes and model years. If you have a question about a specific vehicle or a less common make, call ahead and we'll confirm.
-
No. We give you a written estimate before any work begins. If we find something additional during the repair, we call you before doing anything — you decide how to proceed. The final bill does not exceed what we quoted without your explicit approval.
-
The 24-month/24,000-mile warranty covers parts and labor on qualifying repairs performed at our shop. It's honored at over 14,000 NAPA AutoCare locations nationwide, so you're covered even if a problem with a covered repair surfaces while you're traveling. Ask us at the time of service what's included on your specific repair.
-
Bill's Automotive & Muffler has been on Main Avenue in Twin Falls since 1983 — over forty years serving the same community from the same location.
-
Yes. Federal law — the Magnuson-Moss Warranty Act — states that manufacturers cannot void your factory warranty just because you used an independent shop, as long as the work is performed to manufacturer specifications using appropriate parts. We document all services properly.
-
The 54-point inspection covers nine complete systems — vehicle documentation with photos, wipers and windshield, lighting, heating and cooling, engine and underhood, tires and wheels, brakes, exhaust and underbody, and suspension and steering. You receive a written report of all findings. See our 54-Point Inspection page for the full breakdown.
-
Yes. Bring your vehicle in, we'll assess it and give you a written estimate. No obligation to proceed. We'd rather earn your business by being straight with you than pressure you into a repair you're not ready for.
