When piping one of these Raptors, do you have to re-jet? I have been told yes and I have been told no. Some people say it depends on what pipe your putting on. I dont know for sure. I have been told that the PRO-CIRCUIT T4 is the one to get, is this a wise choice?

pro circuit pipes are okay but if you have a noise level I would say they aren't. My brother and best friend use hmf pipes for your dollar they are the best results i have seen as of yet

I would contact Curtis Sparks... I think he makes very good pipes! Jim

How do I get ahold of Curtis Sparks? Who is he?
