    Ultra Modblaster Pipes

    Anyone have any luck with PSI modblaster pipes on highly modified Ultra motors as compared to Crank Shop, LRM, or HTG pipes? The modblasters are easier to find a good used set.

    i have built and dyno'd alot of ultra's, ultra big bores, and xcr 800. the psi pipes are easy to find because everyone throws them in the corner. all they do is make noise. for a race motor the best pipe for a polaris 800 tripple is the crankshop. i am speaking on dyno numbers and comparisons between all not just my likes. the lrm pipes are good but he likes to spin them at about 10000 rpm and you need a motor ported accordingly to spin that high. hope this helps.
