Exhaust

The Best Gillette Exhaust System & Muffler Repair Services

At Northwest Performance & Machining 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 Northwest Performance & Machining and keep your exhaust system running smoothly. At Northwest Performance & Machining 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 Northwest Performance & Machining today at 905 W 1st 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 Northwest Performance & Machining at 905 W 1st St and we will diagnose the problem right away.
  • O2 Sensor Replacement: Ask any mechanic at Northwest Performance & Machining 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 Northwest Performance & Machining 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 Northwest Performance & Machining 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 Northwest Performance & Machining 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 People Say About Us

    Left my car there while on vacation, kept me informed, car runs great. Fixed a seal, stopped oil leaking, and established I needed a new battery. Thank you, Tracy and Linda Norris!

    Got us in last minute for some repairs that could have been catastrophic if we continued down the road. They could have easily gouged us knowing we were in a pinch and just trying to get home but were upfront, honest and personable. Would recommend to anyone.

    Incredibly impressed with the service and how informative our experience was. They were able to get us in on very short notice and explained to us exactly what was going on with my car. I definitely plan on coming back for any mechanical needs that we may have in the future.

    This shop is absolutely fantastic. These guys went out of their way to fix our problem. We are from Spokane Washington and we needed to get home. These guys worked outside in 30 degree weather to fix our RV so we can make it home. If I'm ever in the area again and need work done these are the first guys that I will go to, to have it completed. The owner even went out of his way to call me to make sure that I made it home okay. Thank you so much for going out of your way to make sure that I made it home and our RV was repaired.

    Cole is great to work with! I had a problem with my wife's care and he was able to find the issue and replace the part. I was able to use the car while we waited for parts. Every aspect of their work was great.

    Friendly, straightforward, and honest. We were just traveling through and I feared some kind of up sell. Nothing like that happened. I wish I lived in Gillette so I could take my car there all the time.
