Lrd pipe

[Hondaguy]

I am asking this question for my friends 400EX. it already has high compresion piston, k+n power kit with holes in the lid, and an FMF powercore4 silencer.
He want to buy the Lrd pipe and want to know if there is a better one out there. or do you guys recomend this pipe. He also wants a full system pipe.

the lrd exhaust is a bad *** pipe. sparks is just a over priced. the lrd is a great pipe for a good price.
