i figured there wouldnt be issues. ive seen a few different 450 pipes from motoworks and they look top notch for sure.Have both but my mid-pipe for the Supertrapp was leaking so am waiting to get another build for it and during that time I'm using my original SR4 which is as good but I just love my Supertrapp sound.
No issues at all with the SR4, if you can, use the PCIII controller with Bo maps and it will run real good.
I have a dmc full exhaust and ehs controller and lid mine is blue does that mean something is wrong? I have black powder on end of exhaust it runs great
