anyone got a Bmc or a viper fitted to a z22?
Yes I have the BMC CDA on my Z22SE but its a bit dodgey due to orientation it doesnt get a true cold air feed as I havent got the pipe to double back on itself. I think you might be better off going for a Dbilas flowmaster/flowpipe setup. Not cheap at E270 though. Havent heard any performance details from them but Regals are selling them so they mustnt be too bad.
