These guys are local and a buddy of mine has an 03 F250 and hes dealt with Xtreme Diesel Performance - XDP Diesel Performance Parts

MBRP 4-Inch Exhaust Stainless Steel (Turbo-Back) - MBS62
Its their 409 stainless single turbo back with 5" tip. for $515.00
I guesss youd have to order the test pipe separate to complete the new kit without the stock cat bolted back on?
Ive heard all these mbrp 4" kits are really 3.5" downpipes? I see lots of you guys have 4-5" full kits, does that mean your downpipe is this big really? Id hate to buy a 3.5" downpiped kit only later to realize it doesnt make much power with one of the SCT tuners and Livewire modules. I mainly tow trailers for my company so racing isnt what im looking for just all out torque while hauling around town :p
