| Motoworks SR4 Carbon Fiber Full Exhaust System for 04 - 07 Yamaha YFZ450
All Motoworks SR4 Exhaust Systems are both dyno and track tested to provide maximum performance. The exhaust is a 100% carbon fiber housing. Stainless steel header pipe, tig welded construction, spring jointed mid-pipe, cnc extruded flange, polished end cap, and USPF approved spark arrestir.
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. |
