Is it a good idea to retorque the head studs to over the factory specs? and can you pull the out of the head one at a time to oil the threads like i saw on a u tube video
I put a MBRP 4 inch exhaust on my 2001 it came 4 inch from the turbo back and was only 258 with no muffler or 358 with a 4 inch muffler. Only took about any hour to put on the truck.
