3.5 in. Mufflers

• Performance exhaust system that provides a classic look in a powerful pipe
• Utilizes stepped header technology that scavenges the exhaust, or draws it out of the cylinder, allowing the engine to operate at peak performance thus making the most horsepower. 
• Fitted with anti-reversion louvers which eliminate the negative pulse from traveling back into the port and robbing the engine of horsepower
• Full coverage, laser cut heat shields providing a clean, sleek look
• Features 12mm & 18mm O2 ports, with optimum placement for dyno tuning and proper measurement of the exhaust gas concentration from the port, making the engine perform efficiently. Also eliminates the need for bung adapters used by other manufacturers which fail to properly place the sensor within the exhaust flow
• Made in the USA
