Mobile Truck Exhaust System Repair Service in Kilgore, TX + 50 Mile Service Radius

Providing Mobile Service In Texas To Tyler, Longview, Marshall, Henderson, Jacksonville, Carthage & more!

While your heavy-duty diesel truck demonstrates impressive capabilities on roads and highways, all that power comes with a price: exhaust. This is where your truck's exhaust system comes in to save the day. It has a dual purpose, which is to safely redirect harmful exhaust gases away from your truck’s cab, and control emissions to keep the air around you clean.

Mechanic performing roadside exhaust system repair on truck in Kilgore, Texas

At Top Flight, we understand the importance of a properly functioning exhaust system for a safe, smooth, and comfortable ride. That's why our technicians give your exhaust system a thorough check-up during every service, using only the best tools and parts to keep your diesel truck in top condition.

As a truck owner or fleet manager, there are some signs of problems associated with exhaust systems to be aware of.

Faulty SCR Catalyst

The SCR Catalyst is a vital component in your engine's emissions control system. It is engineered to turn nitrogen oxides in your exhaust system into benign nitrogen and water. However, if this component starts to malfunction, the signs will be hard to miss - think warning lights on your dashboard or blue smoke from your exhaust. It's also worth noting that the SCR Catalyst is closely connected to the EGR system. So, if the EGR system is encountering issues, it can lead to contamination build-up in the SCR Catalyst. Similarly, if your oil cooler is defective, it can lead to contamination in the SCR Catalyst.

Failing Diesel Oxidation Catalyst

Your Diesel Oxidation Catalyst, much like an SCR catalyst, works to convert emissions from your truck's exhaust into non-toxic carbon dioxide and water. Just as a malfunction in the SCR system triggers warning lights in your exhaust and check engine systems, a problematic DOC causes these warning lights to activate. Prolonged idling or lower-than-normal exhaust temperatures can lead to a build-up of carbon on the DOC's interior walls, requiring comprehensive cleaning to ensure optimal performance.

Gary Roberts

Ram 5500 blew out drivers side front wheel bearing thankfully in Kilgore on a 3000 mile x country work trip. Chose Top Flight. They sent out a wrecker on Sunday evening, took my truck in, and I put up at nearby hotel. Called first thing in the am with parts list and had my truck repaired in a few hours. I was back on the road to home. Excellent service, repairs, and value. I enjoyed your company, to include the wrecker service who dropped me at my hotel. Keep it up!
