Mine will be going to HPC in Leongatha as well. I had some pipes for my bike done at Jet Hot a while back and wasn't real impressed with the results. Difilippo engineering get all their headers done at HPC and the ones I've seen in their factory look spot on.
Phil's getting a MAFless Edit tune from Sam. My prediction after the edit is 300 Rear Wheel HP out of a stock LS1.
Any one want to guess any different?
Cheers
