Lou's manufactures and sells our own custom creation, the Signature Series 409 Muffler. The SS 409 increases horsepower and produces an aggressive, low, deep tone by increasing the internal flow diameter and using thicker 14-gauge aluminized materials.
Our custom system, available in single or dual mufflers, is so popular, we added additional designs to meet the demand. The SS 409 is now available in Truck Pro Turbo, Import Pro Turbo, Dual Muscle Car Pro Turbo, Dual Truck Turbo, and Classic Car SS 409.
There are so many similar vehicles on the road, why not stand out from the crowd? Lou's has a large selection of high quality mufflers and tips in stock for all vehicle makes and models. Stop by and have Lou's Custom Exhaust personalize your ride.
