Based off our design of the Sidewinder, the 2-1 Sidewinder offers a resonated muffler thats all stainless steel coming off a smooth 2-1 merge collector that is a full 2" at the collector inlet and 3" at the muffler tip. This exhaust is compatible with forwards, mids, and rearsets. There are no corrosive materials used on any of our exhausts, so what you are getting will last a lifetime from elements and weathering.
O2 Bungs : If you have a 2007-2018+ Sportster, you will NEED O2 bungs unless you're running O2 eliminators. It's essential for proper air/fuel ratio from your ECM.
Integrated Flange Kit: With our flange kit, you don't have to reuse your OEM flanges. That can be a nuisance because the OEM flanges are snap-ring equipped, requiring special tools and more time to install/remove the exhaust. This adds convenience and less fragile parts to your exhaust system thus, simplifying it all around.
