Exhaust Systems & Muffler Repair
A Quiet Exhaust is More Than a Comfort - It's a Safety Issue
Your exhaust system does more than reduce engine noise. It routes harmful combustion gases safely away from the passenger cabin, helps your engine run efficiently, controls emissions, and contributes to fuel economy. When any part of the system fails, you can hear it, smell it, or see it, and ignoring it puts your health and your wallet at risk.
​
At Double Decker Auto Repair we perform complete exhaust system inspections, repairs, and replacements for all makes and models. From a cracked muffler to a failing catalytic converter, a broken flex pipe, or an exhaust manifold leak, we diagnose the problem accurately and fix it right.
​
Kenosha's road salt and freeze-thaw cycles are notorious for accelerating rust and corrosion on exhaust components, particularly on the underside of the vehicle where moisture pools. If you hear a loud rumbling or hissing, smell exhaust fumes inside the cab, or notice your check engine light is on, it's time for an inspection.
