1320 Performance Exhaust was designed to produce Great low end power all the way to redline while adding an agressive tone to your SlingShot but not annoying loud with drone thanks to our cone shape silencer build in to our muffler. Our exhausts are constructed with high-quality stainless steel, and CNC-machined flanges that accept oem O-ring gasket. Our Anti-Reversion chamber get rid of unwanted exhaust gases that travel backwards through the exhaust system when exhaust gas velocity is low and scavenging is minimal. Under those conditions, exhaust gases can enter the intake side, contaminating the combustion process our Anti-Reversion chamber keeps exhaust flow moving in the right direction resulting in a broader power band and more torque. Factory spring mounting bracket to keep the exhaust in a OEM fitment with no modification required. Our exhaust works with OEM slingshot manifold and our 1320 Performance Header.
