picked up a set of hedman shortys for a deal. would i be better off with running the hedman y pipe and mod it to 3in to mate with my cat and catback or build a custom one thats full 3in off each header and merge to the single. the full 3in may be a little over kill for the lb9 i do plan to keep it as long as possible but when the time comes and it gives up the ghost most likely a 350 will be built and swaped in. i mainly use the car for dd and autocross. also would i be better off putting the o2 bung in the y pipe just after it meets the header or in the header collector? thanks
