All gas and diesel engines produce a number of harmful to breathe gases that can get into your vehicle's interior without a good exhaust system. Exhaust leaks under your vehicle can get into the cabin(interior) through the vehicle heating and cooling air intake system as well as other points of entry. Tri City Auto Repair has a number of options for helping you keep your family safe. We work with multiple aftermarket suppliers, stock the needed parts, and have a custom bending machine to make the needed part if it can't be found.
