Exhaust Repair

An exhaust leak is noise you can hear, fumes you cannot always smell, and on a modern diesel, sensor readings that quietly go wrong. We fix the pipe and everything bolted to it.

Mechanical & Driveline

On a modern diesel, the exhaust is a sensor array

DOC, DPF and SCR components all live in the exhaust, and the pressure and temperature sensors threaded into it drive every regen decision the ECM makes. A leaking clamp or a cracked bellows upstream of a sensor feeds the computer false numbers, and the truck chases regens or derates for a problem that is really a twenty dollar joint.

So we pressure test and repair the plumbing before anyone condemns an aftertreatment component. We also handle the mechanical side: manifold leaks and studs, flex sections, stacks, clamps, brackets and the hangers that vibration keeps breaking.

Questions we hear

Straight answers

Is an exhaust leak dangerous?

It can be. Leaks ahead of the cab can push exhaust gases toward the sleeper, and any leak changes the sensor readings the engine relies on. Small leak, small job; ignored leak, bigger both ways.

Can you make a pipe instead of ordering one?

Yes. Fabrication in-house means odd sections, obsolete parts and custom routing are solvable without a parts backorder.

Why does my diesel keep regening after an exhaust repair elsewhere?

If a joint upstream of the pressure or temperature sensors leaks, the computer sees false readings and regens chase a ghost. We pressure test and fix the plumbing first, then clear the faults.
