Elite Downpipe Installed!!!
Got my Elite downpipe on today. All the hard work was done at Cobb's Diesel Performance. Thanks to John and uga33 we got it done. The stocker is a pain in the as$ and is one of the heaviest, but shortest pieces of exhaust pipe I have ever held.
As far as performance gains, there might have been a slight drop in EGT's. The big thing is boost. I was running the latest 310 tune that Matt sent me 2 days ago. On the way to John's I saw a max psi at around 45-47 psi. On the way back with the Elite downpipe on the truck I saw 52-55 psi on the interstate. So there is definitely something to gain there. Spool up is also much better.
We also noticed a change in exhaust sound, but this could also have a lot to do with the 6" stack that is now on the truck. It does have a throatier sound at idle I must say. All in all I am very happy with the purchase, just gotta be careful on the boost.
