Pipes do make a difference and some pipes will produce much more power.
Of the pipes listed, the Dasa and HMF are the only 2 to consider.
I would consider the Yoshi and sparks pipes to be a great option.

Nope, it's Competition Hill at Glamis, CA. ID has dunes like these? I may have to get out there sometime.

 

honestly they are better!! I've been all around and bar far I like Saint Anthony. If you every make it there go to choke cherry!! huge hill most quads can't make it up!

 

the ltr is fuel injected no need for the jetting. but i have a two bros pipe on mine its sick. the two bros is supposed to be one the of the best pipes right now for the ltr. i also added a cherry bomb and took the airbox lid off. much much more power.
