Motoworks SR4 Full System for Yamaha YFZ 450All Motoworks SR4 Exhaust Systems are both dyno and track tested to provide maximum performance. Constructed from aircraft quality T-304 stainless steel and 6063- T4 aluminum. Motoworks is a new name in ATV exhaust, and as many of the sports top riders and ALL of the competition have discovered, it is the new level by which all others are measured. It's not that difficult to make peak horsepower on the dyno. The challenge is to create an exhaust system that improves performance across the entire power range. Motoworks proprietary headpipe design and performance-tuned canister lengths and diameters create more 'rideable' power, that drives off the bottom and pulls longer and harder through the mid-range and top-end, delivering exceptional acceleration. Match this power with Motoworks 'perfect fit' and unequaled quality and you have something for the magazines to write about. |
