i have LRD and i love it
how can you just names off a pipe. it all depends on the riding style, and motor mods. if hes got a mostly stock motor (reeds, air filter ect) a FMF will do fine. what would he need a Dyno Port High Volume 240 pipe for a stock blaster.
LRD, F7 (porject blaster), and Dyno Ports are all GREAT pipe if you are running a very modified motor. Dont forget there is alot the Vito's Fat Bastard.
i had a toomey on mine with an agressive port job and it worked great, i know that the kid that beat me used a Trenga(LRD) and the guy who came 3rd and 4th used FMF, i think the toomey sounded best out of all of them, the LRD/tenga was realy raspy sounding, sounded mean, and the fmfs sounded flat, tht toomey has a clear, sharp tone to it, and it lays down big power
