Hi,
Okay, Ive seen some comparison product testing on pipe systems for specific ATVs, and they do seem pretty informative and well done.
I havent seen one done yet for the YFZ450 which is what I own. Im told an after market pipe system can boost the power pretty well on my 450 and they all seem to range from $400 to about $750 depending on whether they are made out of steel, aluminum, or out of some ultra-light-weight unobtanium or composite material. Im talking the full system pipe kit. (airbox/filter, jets, pipe) Also, I dont want to break the sound barrier with my new pipe and the spark arrestor must stay on it.
Please feel free to "chime in" with your personal experience and/or wisdom in this area.

Thanx,
Plad

 

Hopefully I will know tomorrow. My FatBoy 4 exhaust should arrive tomorrow. Comes with the jet kit and K&N set up for $510.00. If it arrives tomorrow I'll have it on and running and let you know how it goes!

 

Thx Solo,
Good luck with the install, man.
