I'll be setting up my XF with 250 Xflow for daily use, with broad torque in mind. Engine will stay stock aside from a towing/lpg cam, a bit of headwork and maybe roller rockers.
I have a set of Pacemaker headers, and thinking of going a 2 and a quarter inch piping from there all the way to the tip. I'll run a high flow cat, a hotdog and a straight through oval muffler.
Most people run the muffler in the middle, then the hotdog up the back. What are the advantages/disadvantages if i run the hotdog in the middle and the muffler at the rear?
I'm not fussed about exhaust DB, or if it cackles on downshifting. I'm not a fan of drone, though I have a T5 so I can get the revs low on the freeway.
Is 2.25" piping good for what I have in mind? And does anyone have a exhaust clip of an alloy head 250 Xflow with a tow/lpg cam?
