Hi everyone. Just posting some updates. Put in the 5" exhaust without the muffler. The truck is quiet at idle, but roars when under throttle. So basically, I have the Spartan 210 tune and a dpf back 5" exhaust. You can constantly here the turbos through the exhaust outlet, even at idle.
I did the work at my friends race car shop where tons of diesel trucks exist for hauling our toys (race cars). I was pleased with the power in my 2008 F250 till my friends showed me their power gains in their 2001 to 2004 trucks (GM and Ford). I would say mine is the slowest and has the least power. Even though its quick, Its not as quick as my friends trucks, that are duallies with similar mods. I am wondering if something is wrong with mine at this point.
As for mileage. The truck seems to be doing much better fuel wise, but I have a heavy foot so I wont know for some time the real numbers.
