Exhaust Accessories Depending on the type of motorcycle you have there are a number of options for adding custom accessories to both a stock OEM exhaust and an aftermarket exhaust system. Cruiser motorcycles, touring bikes, sport motorbikes, dirt bikes and even ATV's all have the option for adding custom high performance exhaust accessories including fuel kits and quiet module inserts to get better performance out of your exhaust system. Many professional racers and mechanics will tell you the first accessory you should invest in when replacing a stock OEM exhaust system is a fuel management system. High performance fuel card kits act to harmonize the air flow and fuel in your pipes to produce a smoother ride. A quality fuel kit will also help to prevent deterioration within the exhaust system giving your bike longer life. Depending on the type of exhaust system your bike has you may also consider adding special cut drag pipes to Harley-Davidson's, Honda and Yamaha cruiser motorcycles and Suzuki Intruders. Drag pipes are added to stock exhaust systems to increase the horsepower of the bike in the mid-range level, give the bike a polished chrome look and produce a growling sound that is synonymous with big hog cruiser motorcycles. Drag pipes are available in straight cut and slash cut designs and also pipes that turn downward for a unique look.
