I am putting on an aftermarket up pipe and down pipe on my WRX and getting it COBB tuned with a custom map and fine tuned by my tuner. I am planning in putting on the up pipe/down pipe myself. That being said, I will need to drive it to the tuner after making upgrades without a tune. How/what order should I do things? Bolt ons, Accessport tune, then drive to tuner to get custom map/tune? Or what?
Also if I upgrade up pipe and downpipe without upgrading the rest of my exhaust will I blow it or can I safely do this? Thanks
