Lou's Signature Series 
At Lou's we are constantly looking for new products and better material to offer to our customers. In 2006, we developed our new Signature Series mufflers - a new innovative line of mufflers developed for our performance customers.
2–Chamber High Performance Mufflers
With 40 years of experience installing muffler systems, we determined that we could create a better muffler using our own design and manufacturing process. The 2–Chamber SS muffler was designed for our customer interested in performance gains and well as an aggressive deep tone. This was accomplished by increasing the internal flow diameter and using thicker 14-gauge aluminized material (industry standard is thinner 16-gauge). The result is our most aggressive sounding performance muffler.
SS 409 Pro Turbo Stainless Mufflers
Classic car enthusiasts have continuously asked for a deep performance tone muffler without the loud resonance in the vehicle created by many of the highly advertised mufflers on the market. We took the challenge to create a muffler that increased horsepower and at the same time produced a low deeper tone. The SS 409 Pro Turbo stainless muffler has become so popular we have added additional designs to this popular design.
The SS 409 Pro Turbo is now available in a Truck Pro Turbo, Import Pro Turbo, Dual Muscle Car Pro Turbo, Dual Truck Turbo as well as the original Classic Car SS 409.
