Yfz 450 Monsterpipe Big Bore Dual Core Gen 2

This is the new Big Bore Dual Core Generation 2 Monsterpipe from Monsterquad atv products. This pipe comes with 2 different cores for different engine types and different power requirements. For smaller bore motors you would use the regular core with the reverse megaphone billet peice. This gives you more low end torque for MX and trail riding. For all out horsepower or for big motors, switch the core to the Big core! We have run these on motors as small as 450cc's and as big as 523cc's! It is the best inframe pipe that we have ever dyno tested! It also has some great features. The headpipe is stainless steel, the inlet and outletsw are billet aluminum and it uses a billet aluminum bracket to mount it. The inlet also is spring mounted to give the need flex of the system so it won't break the mounts under heavy vibrations. It is available for the 04-08 Yfz450 and the new 09 Yfz450r. It is available in black or brushed aluminum. You can order with the single core in which you must specify which one you would like or for $20.00 more, get both cores!
