We do it all. We do it better. We do it for less.

Specializing strictly on exhaust work, the experts at Lou’s Custom Exhaust have created a bit of an empire. Sure, it may sound as if we’re tooting our own horn, but we’ve earned it. For nearly three decades, our family-owned business has earned the trust of local residents for honest, quality work at affordable pricing.

Unlike other shops, if it’s not broken, we’re not going to fix it. At Lou’s, we can replace small components without the need of replacing a complete system. Under car exhaust components, flex pipes, muffler replacement or repair, exhaust manifolds – dump truck or Smart Car – no job is too big or too small for our team.

If you’re looking for a local exhaust shop you can rely on, you’ve come to the right place.

Catalytic Converters

Converting toxic gases from your vehicle’s engine, the catalytic converter is essentially an emissions control device.

Flex Pipes

As an essential part of nearly all front wheel and all wheel drive vehicles, having an auto shop that specializes in flex pipes is a must.

Mufflers

Designed to reduce noise, a faulty muffler often produces an unpleasant driving experience.

Exhaust Manifolds

Strange noises, unusual odors, and most of all – performance loss are all signs of a cracked exhaust manifold requiring repair.
