I Got the Grimmspeed downpipe which was about 360 compared to 595 for the cobb downpipe. The only difference was the grimmspeed has no cat. and it came with all the Gaskets!!!!! I ended up just having them put the downpipe in so I could have it for the drive home

i live about 3 hours out of portland. The guys at surgeline where very helpful and I would definately recommend them to anybody. I have the accessport on stage 2 and DAMNNNNNNN what a difference. Definately was a fun drive down I-5.
and its fun checkin out all the sti's they had there and the 350z and the gt-r
