Exhaust, Columbia, MO

The Best Columbia Exhaust System & Muffler Repair Services

At Walt's Service Inc. we know some drivers like a quiet exhaust system while others prefer a "the louder the better" approach. Either way, an unusual rattle when your car is running is a signal that it is time for an immediate inspection of your exhaust system.

Quiet Exhaust and Muffler Services

Come to Walt's Service Inc. and keep your exhaust system running smoothly. At Walt's Service Inc. we know you count on your exhaust system and muffler to reduce noise and normalize your engine's back-pressure. When your exhaust system is faulty it can be very loud, but more importantly, it can impact your engine performance. Whatever the problem, we can repair it and get you back on the road quickly. Come by Walt's Service Inc. today at 1204 N College Ave.

  • Catalytic Converter Replacement: Your catalytic converter is the most expensive part of your exhaust system. When your catalytic converter begins to fail, you will hear a very loud rattling noise or your "check engine light" will begin to flash. Come by Walt's Service Inc. at 1204 N College Ave and we will diagnose the problem right away.
  • O2 Sensor Replacement: Ask any mechanic at Walt's Service Inc. and they will tell you to have your O2 sensor inspected regularly. Oxygen sensors work in conjunction with your catalytic converter to monitor the amount of oxygen in your car's exhaust system. Your O2 sensor determines if your air to fuel ratio is balanced in real-time as you accelerate or idle. It helps your engine controller adjust the flow of fuel to maintain optimum oxygen to fuel mixture.

High-Performance Header Upgrades

While exhaust manifolds and headers play a similar role, at Walt's Service Inc. we know they are miles apart on performance. Headers are upgrade parts designed for performance applications, while exhaust manifolds come standard. Both move exhaust away from the cylinder head to the exhaust pipe. Most noticeably, headers and its companion gaskets and wider exhaust pipe are much louder than a traditional manifold. But more importantly, the header improves exhaust system performance.

Exhaust manifolds are frequently formed of cast iron. The cast iron construction of your manifold keeps exhaust from being cleared as efficiently as possible. Headers solve this problem as they are made of individual steel tubes that connect to each cylinder. Header tubes all connect to a single collector pipe. The tubes have a smooth interior that keeps gases flowing evenly to prevent engine back-pressure. If you want the performance of a header but the sound is a problem, talk to our mechanics at Walt's Service Inc. about an electric exhaust cutout. They are simple to install and allow you to open your exhaust without crawling under your car.

Get The Look Of Custom Exhaust Tubing & Tips

Straight, U, J, and S exhaust tubing are made with a smooth stainless steel or mild steel aluminized metal interior for maximum exhaust flow. At Walt's Service Inc. exhaust tubing can be configured for a custom exhaust system. Stainless steel exhaust tubing looks sharp and adds longevity to your exhaust system. Complete the look with stylish exhaust tips. Nothing finishes an exhaust pipe better than the crisp clean appearance of a polished stainless steel exhaust pipe tip.

Loud Exhaust and Muffler Services

X-pipe and H-pipes synchronize the balance of the exhaust pulses from each cylinder based on firing order to increase efficiency. Many high-performance car owners like the deeper rumbling sound of H-pipes. If you own a street rod, Lake Pipes and Side Pipes route exhaust along or beside the bottom of your car body offering both increased performance, vintage look, and an aggressive sound. When it comes to trucks and diesel, consider smoke stack exhaust pipes to improve engine efficiency, pulling power and performance.


What Our Customers Are Saying

Was driving from NY to LA when my Bus started dying on the highway. Lookup the nearest VW mechanic and come here. Walt is great! He took a look at my Bus, even though it was late and he was busy-and told me the last guy who rebuilt the engine screwed up. I trusted Walt to rebuild the engine, and he did it cheaper and quicker than the first mechanic, and much better! I now have 10-15mph higher top speed and it runs a lot smoother. Driving from MO to LA I went from losing 1qt/1000 miles to losing no oil! Superb job, honest guy, nobody knows more about air-cooled VWs than he.

My daughter, a MU student, and her used 2007 high mileage Audi A4 broke down, the car was towed to Walt's. Walt called me the next day and went over his diagnostics and recommendations. He only recommended what needed to be done and did not recommend useless/costly repairs. When the car was complete, he called me with the final bill which was totally reasonable. He was timely and great to work with! I highly recommend this repair shop, it is so hard to find honest and qualified technicians and mechanics these days and Walt is truly one of the best I have ever worked with. I will definitely be back, thank you so much!

I have an old (2001) high mileage (155k+) VW Golf, and I only take it to Walt's. The staff is friendly, honest, fair, and fairly quick with repairs. They give you options and explain the pros and cons of optional repairs. They keep my old Golf running well, with fair costs for repairs. I would (and have) recommended to anyone with a VW or similar German car.

I had my MINI Cooper serviced here. These guys are great. They showed me everything about my car (as I know nothing about cars). The Baron MINI in Kansas City told me I needed new front and back brakes and rotors. After showing me how much brake pad I had left on the back brakes, the guy at Walt's said "that's nuts and these should last at least another year". They also did quality work and cost a couple hundred bucks less! I am very pleased!

I have seen the work they do on Porsche 911's, many times, first hand. They are friendly and helpful. Very knowledgeable staff. If they tell you something, listen to them. The best Porsche service in MO.

To say that Walt is honest would be the understatement of the century! As a female, I'm always nervous about being taken advantage of. And with a 2005 BMW Z4, sometimes work needs to be done!Thank you Walt. You have created a loyal customer.

This place is trustworthy, dependable and communicates everything to you very well. I graduated from MU and now drive all the way from Saint Louis so that I can get my car serviced at this location. No other service center can compare to these guys.

A good shop with experienced techs and good labor rate compared to larger places. They know what they are doing!

Walt's shop has worked on three of my vehicles during the past couple of years. Results were excellent, and I found their prices competitive with other shops in the area. Everyone there is helpful and courteous. My vehicles include domestic brand trucks and SUV's so be aware Walt's work is not limited to just imported models.

This shop has been consistently top notch for service, honesty, and pricing. Although the specialize in foreign cars, I also take my other vehicles to them, as well. I highly recommend them.
