I'm heading to my shop at college and will have plenty of time to weld up flanges and 2.5" pipe for one, will I see any gains? BTW I put this in this forum because I only want to hear from boosted people. I'm running a Star kit w/ 1g SMIC and 2.5" exhaust w/ hi-flow cat so I do have a slightly larger DP then the HRC guys, but will the notice be worth the time to make it?
