im narrowed down to either rocket or shearer pipes. i plan on buying a set before next race season. but i gotta see a dyno on them and how they compare to other pipes like cpi, t5's, t6's, lrd, and trinity.....i really like both rocket and shearer and a guy i talked claimed shearer pipes put out 2hp more then rockets on a dyno im still gonna wait for some results on people who ran both to see there comments im sure there all good pipes though!
