Increased riding comfort while maintaining the stock look. Heat from the exhaust system can become uncomfortable, especially riding in slow traffic. This issue really comes into focus for those with shorter legs. Not wanting to disrupt the attractive lines and appearance of the exhaust, DEI's Heat Shield Liner Kit insulates the outer heat shield, without disturbing the looks of the bike. Each piece is precision cut to fit in-between the exhaust pipe and the heat shield, blocking heat transfer and lowering the surface temperatures of the outer shield. Easy to install, with no permanent modifications needed. The Heat Shield Liners are dual layer constructed of Aluminum and our proprietary Dura 2000(TM) insulating material and offer over a 60% reduction in heat. Features CNC cut for a perfect fit Completely hidden when installed Advantages Durable long-lasting materials Simple installation No smoke or odor Benefits Reduces heat radiating from the exhaust system, giving the rider and passenger a cooler ride. This is especially noticeable when the rider stops and puts their feet on the ground. Note: Heat Shield Liners install inside the head pipe heat shields. Please pay attention to what brand head pipe you are running not the brand of the mufflers. Kits are compatible with black or chrome head pipes.
