Exhaust, Saint Charles, MO

The Best Saint Charles Exhaust System & Muffler Repair Services

At Kar Tech 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 Kar Tech and keep your exhaust system running smoothly. At Kar Tech 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 Kar Tech today at 4600 Central School Rd.

  • 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 Kar Tech at 4600 Central School Rd and we will diagnose the problem right away.
  • O2 Sensor Replacement: Ask any mechanic at Kar Tech 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 Kar Tech 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 Kar Tech 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 Kar Tech 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.
