Exhaust

The Best Charlotte Exhaust System & Muffler Repair Services

At Interstate Motor & Auto Service 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 Interstate Motor & Auto Service and keep your exhaust system running smoothly. At Interstate Motor & Auto Service 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 Interstate Motor & Auto Service today at 9800 Newell Hickory Grove Road.

  • 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 Interstate Motor & Auto Service at 9800 Newell Hickory Grove Road and we will diagnose the problem right away.
  • O2 Sensor Replacement: Ask any mechanic at Interstate Motor & Auto Service 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 Interstate Motor & Auto Service 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 Interstate Motor & Auto Service 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 Interstate Motor & Auto Service 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.

    Great place to get your automobile serviced.

    This is, in my opinion, the BEST family-owned mechanic shop in Charlotte, probably all of NC. The owner, Beaver, is the most honest, honorable, and direct person I've ever met in this business. He expects the same traits in his staff. Youll never have to worry about them trying to "pad" your estimate.

    I really liked their honesty they told me what I should do to get my car fix instead of trying to do it knowing they couldn't get it fix just to get the money !! If I ever need my transmission done I for sure will go to this place also the people that work there are very kind and helpful !!!

    Took my wifes Element in for front wheel noise. I thought it was wheel bearings or the calipers weren't releasing fully. Chris test drove it and couldn't get it to make any noise. He said the bearings and calipers were fine. In fact he told me the calipers had been replaced. He said he could replace the rotors and pads but couldn't guarantee it would stop the noise. You can't go wrong with doing normal maintenance a little early on the wifes car. The mystery noise went away. They had every opportunity to take advantage and didn't. I appreciate their honesty and will have all my maintenance and repairs done here from now on. Highly recommend! Thanks guys!
