Well dropped the truck off today. Should have it back next weekend if I can get the time off work to pick it up. Problem I ran into with crossover pipe was it wouldn't clear my front driveshaft. Curious if anyone else has had this problem with the on 3 kit in their 4wd. Try to get some finished pics up when I get it back. Haven't had much time between work.

 

What's everyone running for an exhaust. Thinking about just keeping my Flowmaster or should I go with something more straight through? Was going to go with 3" or should I go bigger?

 

updates? I would go with a straight through muffler.

 

Ended up buying a magnaflow. Truck is still at the shop/tuner getting finished as I have no time now due to my work schedule. As soon as it's finished I will post dyno results and pics.

 

Ok sorry for such a delay in this build. I ended up getting a better job offer and moving etc in the past few months so i've been busy. The truck is finished and heres the results:

 

Now on to the real stuff. Pretty sure in the mist of all this one of my pistons didn't like the new turbo set up. So the motor has a knock to it. I will be laid off from my job within the next 2 months. I plan to pull the motor and do a rebuild. Thinking some forged pistons and rods with a head job would beef this thing up a little. Can anyone point me in the direction for a good set up?

 

Also my tuner said he had the truck up and over 540hp on the dyno but didnt include that print out.

 

Would it be worth picking up a pair of ls6 heads or should I just save the money and put it into my 5.3 heads?

 

If your heads are 799 castings they're the same as the ls6 243 heads

 

Thanks for the info. Going to keep the same heads.
