HI ALL have a twin turbo with hybrid turbo's high lift cams blitz induction kit ( I know ) Blitz intercooler F1 com ECU controller which I have owned for approx 1 month pushing somewhere over 400 BHP not dyno'd yet, currently have a 5 inch pipe manifold back but this will not handle the power as it is forcing the internals of the silencer out of the tailpipe CAN SOMEONE PLEASE RECOMMEND an exhaust capable of handling at least 600BHP that will also look and sound the part. Also looking for DUMP VALVE are they any good, do they kill turbo's and which are the BEST????? HELP WOULD BE REALLY APPRECIATED:rolleyes:
