I made a few small changes to the truck this weekend and all I can say is wow. I had the cats cut off and I put the .96ar housing on my MPT70 and it made a big difference. The 6.0L spools this setup very quick even with the bigger housing and it pulls like a freight train all the way through the power band now. At 6psi it will blow the tires off from a 30mph roll when it downshift to 1st and on 10psi it will spin in second from a 50mph roll. The only complaint so far is that it is way too loud without the cats so I going to put a magnaflow bullet style muffler before the turbo to take away the rasp.

i'd be anxious to hear what it sounds like. mine can be deafening at 20psi.

It actually sounds good at wot but it sounds like crap at part throttle cruising around town.

Iv had a Magnaflow infront of my STS since i put the kit on... I think thats whats causing the deep noise in the cab.. so i put a smaller Magnaflow after the turbo and it just sounds like a NA truck now until the wastegate opens..

When i get time, i want to remove the front Magnaflow and leave the one on the back.. If that doesnt sound good im goin to copy Spoolin's setup.. or just not run a muffler cause i loved the whistle it use to make!!!

I liked the smaller housing on the 5.3L but the bigger housing pulls better on the 6.0L.

That is a nice setup.

I know... thats what i want to do..
There is a Flowmaster in that pic, but now he has a stock 2500 muffler..
Id like to do that one day to keep it quiet as stock, but still have the "Nasty Switch"
