exhaust pipe size question
I have bbk longtube headers which have 2 3/4 collectors at the end and bbk catted x pipe which is 2 3/4 piping but the over the axle pipes that start after the xpipe and go to the axlebacks is that suppose to be 2 1/2 or 2 1/4? I cant remember and thought i seen the borla ataks with both 2 1/4 and 2 1/2 inlets for the 11+ mustang v6. anyone have the MRT catted H pipe? im still trying to decide if i wanna replace the bbk x pipe for the MRT h pipe.
