I know AEV and Burnsville makes them. JSS has one too I think. What's the best route. I can't find much info on Burnsvilles kit. I don't need the full install kit with exhaust from AEV since i'll be doing my own custom exhaust. Any other options out there? I'll be going with a 5.7vvt pretty soon and I need to plan this out good. Any input would be great. Thanks.
