Looking to buy my lil brother a pipe for his stock 03 warrior. Looking at HMF or pro circuit t4. Are thes two pipes pretty much the same in more overall improvement to a stock warrior. I know nothing on four strokes. Is it also true that the stock header pipe is perfect and aftermarket ones dont really do anything but cost ya an arm n leg!!?? preffer two-stokes my self!! Thanks

 

My freind has a T4 on his warrior, and its jetted correctly and shows a nice overall increase in power. Mostly down low and midrange. HMF is also a very good pipe, but cant speak for it because ive never seen one on a warrior. I prefer 2 strokes as well, im looking for a banshee.

 

HMF is an awesome pipe, tell him to order from sweetquads.com
