I know this has been an on going thread but i was thinking of buying a delete pipe i think it bolts up to the stock down pipe? then from that flage weld a reducer down to 4 inch and put a 6.0 cat back exhaust since they r cheaper? what do ya think? Also what about the sensors? still need to be plugd in i saw 3 sensors 2 where the delete pipe will go then 1 back after the muffler? what do you do with that one, weld a threaded bung and scew it on the new exhaust
