What do you guys recommend? I've been eye-balling the Yoshimura TRS Pro and the Trinity systems. I plan on using the K&N Max Flow set-up from Alba without the airbox lid and may install a different cam(s) one day. I want to get the best. Trinity's web site says their pipe is R&D'd to get better the more mods you add. I don't see how the Yosh pro system could hinder future mods. Any opinions and advice would be appreciated.
