Exhaust

The Best Miami Exhaust System & Muffler Repair Services

At AGT Imports D/B/A J&M Auto Doctors 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 AGT Imports D/B/A J&M Auto Doctors and keep your exhaust system running smoothly. At AGT Imports D/B/A J&M Auto Doctors 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 AGT Imports D/B/A J&M Auto Doctors today at 1928 NE 151st.

  • 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 AGT Imports D/B/A J&M Auto Doctors at 1928 NE 151st and we will diagnose the problem right away.
  • O2 Sensor Replacement: Ask any mechanic at AGT Imports D/B/A J&M Auto Doctors 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 AGT Imports D/B/A J&M Auto Doctors 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 AGT Imports D/B/A J&M Auto Doctors 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 AGT Imports D/B/A J&M Auto Doctors 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.

Testimonials

  • I brought my 2003 BMW 530i into AGT because I was deciding whether or not to sell it. It had some problems that I thought would cost thousands to fix even though it has low miles and is very clean. Gus and his team fixed all outstanding issues for far less than I expected to pay, and when I (dumbly) rode into curb the next day and half pulled the bumper off, they fixed that free of charge. My friend had a similar experience with her Mercedes. Clean shop, efficient service and great people. A strong recommend.

  • Gus is the real deal. When I lived here in Miami, I started using his service at the recommendation of one of my co-workers. I have continued to use his service now for over 20 years and continue to be thrilled with not only the level of technical competence, and the delivery of service, but the honesty and fair pricing for all work. I have referred all of my friends to Gus over the years.

  • I had a great experience. Took my car in for a regular service and got out in less than an hour. Gus is a pleasant guy to deal with. For a regular service, I saved plenty of $$'s over what dealerships were quoting.
