i will next day im off my egts are 1200 unloaded going up slight hills about 60 so i gotta do the exhaust so i can start working the truck im thinking a down pipe and 4" or 5" turbo back straight piped, i have like 5 jobs to do but i cant pull the tractor yet im also getting crappy fuel mileage like 10 and i think both issues are from the cat and muffler being completely compacted with suit from that rag

when my cat plugged up the milage took a dump. once i got my 5" exhaust mileage came back. i think the new exhaust will do it some good.
