    Catalytic Converters

    Converting toxic gases from your vehicle’s engine, the catalytic converter is essentially an emissions control device. This component reduces and oxidizes gases that are not only harmful to the environment but also to humans. However (if that wasn’t a big enough job), the catalytic converter also improves the efficiency and performance of your vehicle.

    As you can see, this little piece of the puzzle plays quite the role. Thus, having a fully functioning catalytic converter is a must. If it’s performance you seek, the specialists at Lou’s Custom Exhaust are your solution.

    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. Lucky for you, you’ve found Lou’s Custom Exhaust! Here, we specialize in replacing only what is needed. With the latest technologies, our specialists are empowered to remove old flex pipe and weld in a new one at a fraction of the cost from other exhaust shops.

    Mufflers

    Whether it is muffler repair or muffler replacement that your vehicle requires, our team is here to help. Designed to reduce noise, a faulty muffler often produces an unpleasant driving experience. Sure, we love a good rumble as much as the next guy, but not from a failing component!

    Because the muffler is connected to other elements within the exhaust system, it can sometimes be damaged along with other components. Addressing all issues at once is the best way to avoid repeat trips back to the shop. Thus, saving you time. At Lou’s Custom Exhaust, our experts will take the time to diagnose the problem and inspect other areas that may be connected.

    Exhaust Manifolds

    Strange noises, unusual odors, and most of all – performance loss are all signs of a cracked exhaust manifold requiring repair. Acting as the bridge between the engine’s emissions and the rest of the exhaust system, manifold repair should never be put to the side.

    At Lou’s Custom Exhaust, our team of experts understands the ins and outs and every piece in between when it comes to manifolds. No matter what the issue may be, we can help remedy the problem. With in-house machinery, our shop is empowered to provide budget-friendly solutions to the damaged components. How is this different?
