If you go external wastegate then a downpipe from HKS is $150-175 new. If not going EWG then dont use HKS DP (it has a flat flange over IWG area of turbo). Otherwise, I figured there has to be decent parts from the UK like ScoobySport (exhaust note hall of fame). Downpipe from them is $119 lbs. or approx $250 USD.
