Exhaust

Exhaust, Rockville, MD

The Best Rockville Exhaust System & Muffler Repair Services

At Golden Gears Automotive, 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 Golden Gears Automotive, Inc and keep your exhaust system running smoothly. At Golden Gears Automotive, 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 Golden Gears Automotive, Inc today at 12025 Nebel St.

  • 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 Golden Gears Automotive, Inc at 12025 Nebel St and we will diagnose the problem right away.
  • O2 Sensor Replacement: Ask any mechanic at Golden Gears Automotive, 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 Golden Gears Automotive, 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 Golden Gears Automotive, 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 Golden Gears Automotive, 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

Sam helped me with the transmission. I was hesitant if I should replace it as my car had 100,000 miles. He worked with me. Thank you-

Sam and his team are wonderful! He is honest, fair and will go out of his way to find the best solution to any issue your car may have. Sam is courteous and generous, and I highly recommend Golden Gears. I teach at a school nearby and we ALL take our cars to him. I just picked up my car from his spotless workshop, and Sam found a cosmetic flaw which he fixed on the spot, free of charge. Golden Gears is a treasure.

reviewicon

I usually choose a garage based on recommendations from friends, but took a chance and went to Golden Gears based on online reviews. The Maryland inspection went well and the price was very reasonable. The owner recommended that the tires be rotated, which I knew needed to be done as I had incorrectly moved the newer tires to the back of the car when I rotated them myself. Based on this experience, I trust this shop and plan to return for maintenance and repairs.

Fabulous experience. I think I've found a car repairman to go to for the rest of my life. Competent, kind, and fairly priced.
