well I read on here about 1 guy who likes the borla header with the cobb stage 2 setup. I currently have upipe, 3" turboback exhaust, intercooler hoses. so i've read somewhat about the maybe the 5hp gains, and i've read the header info from nasioc. but i just want some input from the guys who have this setup if you've dynoed, and what kind of track numbers you pull, etc. thanks!
