Exhaust

The Best Tucson Exhaust System & Muffler Repair Services

At Covenant Automotive Repair & 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 Covenant Automotive Repair & Service and keep your exhaust system running smoothly. At Covenant Automotive Repair & 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 Covenant Automotive Repair & Service today at 4950 E Speedway Blvd.

  • 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 Covenant Automotive Repair & Service at 4950 E Speedway Blvd and we will diagnose the problem right away.
  • O2 Sensor Replacement: Ask any mechanic at Covenant Automotive Repair & 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 Covenant Automotive Repair & 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 Covenant Automotive Repair & 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 Covenant Automotive Repair & 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.

Testimonials

  • We found our former auto repair shop closed only to "randomly" pull into Mark Knaak's, Covenant Automotive, LLC today. While it makes sense to get an appointment, they performed mechanical service on two of our cars without hesitation. They were pleasant to work with, asked appropriate questions, provided information and excellent service second to none. Mark is a VERY experienced mechanic and able to work on almost ANY make or model. He specializes in "high end" luxury vehicles. Raise your prices, Mark! You deserve EVERY penny. THANK YOU. We'll be back!

  • Mark was honest, kind, worked very efficiently, and made my experience at Covenant Automotive not only enjoyable but heaven sent. I will certainly be taking my Nissan to him and his team as long as they are in business in Tucson. Thank you Mark for your kind heart and excellent service!

  • Very impressed! I just dropped in before 3pm on 2/19/2018 with my 2001 F150 Lariat, thinking I might need a fuel filter replacement..."Service Engine Soon" light was lit. When they checked, it was determined the truck was misfiring on #8. I thought I'd have to arrange another day to bring it in for the estimated 3 hour job; Mark assured me that he could get two guys to work on it right away, and if they had to go a little past 5, they'd do whatever was needed to get me going. Well, a whole set of plugs and a new coil, and they finished at 4:50! Amazing work!

  • My stepdad brings in our cars to Mark and he does a fabulous job taking care of them! I took my Nissan Maxima in for an oil change and to get my splash guard nailed back into place. They took excellent care of my car and I am very impressed with them! Will be back with my husband's car for an oil change, and will keep coming back! The oil change is a great price for the service that you receive!

  • My 2000 GMC 1500 SLT 2WD with 147K original miles had developed a popping sound in the frt left side while I was visiting in Tucson, and being a bit of a motorhead from years past, I had a good idea as to what it was. I took it into a well known national chain garage to do an inspection, not only did they charge me $20 to do the inspection, they quoted me well over $2300 to complete the work. Then I did a little web search and found Covenant Automotive which is backed by NAPA so I called made an appt. I took it in as scheduled and they got right on it, doing the inspection and working up a quote, that is when Mark told me that he would quote the job in the most economical manner, which meant replacing the entire upper arm rather than replacing the bushings and the ball joint separately on both sides, as well as the tie rods on both sides. He quoted me $1017 and change which also included an alignment. They took me back to the RV Park where I was staying and finish! ed the work as promised, on time and on budget! I have driven the truck now for a few weeks, took a 500 mile road trip and I am completely satisfied with the quality level of their work. Mark and his team are not just mechanics, they are motorheads themselves and it is in their blood, they will work on your car or truck as if it was their own and they take great pride in their commitment to their customers My thanks to the team at Covenant Automotive, and Happy New Year!

  • All I can say is I wish you were here in Amarillo where I just moved. I've never had such good service from anyone, and I am a real skeptic when it comes to mechanics. You and your crew are the best. Thank you!
