Kudos to skunk2 for building such an awesome header / downpipe. The install was easy, took my time. Got it done over the weekend and then off to take it for a spin. Wow the power difference is just huge. I got the flashpro like hardmotion tech help suggested and loaded up a basemap built for this setup and it just had so much more power and felt overall just better.
Excellent downpipe, great pricing
