OK I have put the K&N filter in I am putting in the PCIII and I am about to install the 4-1 Yoshimura TRD system. I have read so much about the pair valve removal and mod., even about relocating it. Which is the best route to go? Should I totally take it off, find out where or how to relocate it on the new system or just pop the marble in? I have the 2 brothers slip ons on there now and even after remapping it (factor computer) it still has the popping back fire. Not real bad and not all the time but it does do it. I would like to try and prevent that if I can while I have it all apart. I will be doing it in 2 weeks.
Thanks,
Mike
