RE: Lookin for a possible new hull
the QD pipes are available as kits too so you can weld them up yourself, only $60us for a kit
a standard type pipe with a deep vee type header may work if you don't mind losing a few kph, that type header is usually a bit too long to tune the pipe for max performance
but either way like mart says it may not even fit, i have seen a pipe inside a pretty small hull though
