Review on 🏍️ Enhanced Performance & Noise Reduction: MASO Universal 60mm Motorcycle Exhaust Muffler Pipe with DB Killer Silencer by Charles Woods

My stock Harley mufflers had too much back pressure, reducing power and generating more heat for the engine. Thought I needed an oil cooler. I had a pair of Screaming Eagle 2 Slip-Ons but the baffle was removed. Too loud. Found a Maso baffle that seemed to reduce noise and allow airflow. The largest Maso size was 60mm, which was about 1/4 inch smaller than the existing holes. The baffle mates with the existing muffler inner liner and wire mesh. I was lucky, it was exactly 60 mm. Some modifications later. Has a noise-damping effect, but still lets a lot of air through and still sounds great. I restored my performance and reduced engine heat around town. Be prepared, they're cheaply made.
