Ok here is the thing I ride in nothing but sand dunes so I stay mostly in the mid to top end I am on the market to buy a new set of pipes for my bike mods are in my Sig that being said I'm really leaning towards the R2's but I have read nothing but good things about Shearers and CPI's I want to hear your thoughts and choices on what pipes are the best all around pipe and any info on dyno comparisons or actual experience in the comparison of these pipes
