Episode 4 is all about exhaust. Wings is the premier exhaust upgrade for the Husqvarna 701. They also make exhausts for KTM, Honda and Yamaha. This is a titanium-carbon exhaust that saves you 6 lbs off the stock boat anchor. The weight saving is due in part to the elimination of the catalytic converter from the stock exhaust. This exhaust really opens the engine up to let it breath. This enables the 701 to deliver more power and torque, in addition to the amazing sound. It comes with two db-killers with spark arrestors, which giveS you a choice of a loud or louder sound. We love this exhaust and give it a 10/10 for fit, finish and sound! – www.wings-exhausts.com
