i have searched and couldnt find a conclusive answer, what size is the lsj dp? is it 2.25" like the cat bck or is it 2.5"???? im buying a pacesetter header and i do nt want to weld it onto my stock dp due to the size of it, i wanted to see if the lsj was a 2.25", cuz the collector that comes with the pacesetter is 2.25", what size is the stock 2.2??? cuz i would much rather have a straight thru 2.25 all the way, incase the lsj is 2.5, i already have the lsj catback
