Hey Jason I wasn't sure if I should email you or not. But I was wondering if you could answer a few questions? I have a 98 Z28 with an slp lid, granatelli mass air and a ported throttle body. I put hooker long tubes and a 3" inch y-pipe. You are the only person I know that has done this similar set up with jet hot LT's. and then dynoed it to show the gains. Could you tell me what y-pipe you used, and then did you go to a sigle pipe to your muffler? what size? and what muffler? cuz right now My hp and torque gains are definately not there. more like a loss. Sorry for so many questions. Im just trying to save a few bucks.
