Bought several thing from him, great on help and advise. Currently getting ready to put his headers on and will report on fit. (got to get finished putting my Gbody SS T-top parts on). I was running his downpipe and wastegate which held to a quarter of a pound, until I put on the FAST XFI and now I am going with his larger set up. He prewelded the wastegate tube and the wideband fitting for me before he shipped the parts, can not ask for better support. (well except for Jack and I am putting his name in for sainthood.)
