MBRP TB exhaust

The reason the DP wont work is the 03-04's have a 3.5" oulet on the turbo and your truck has a 4". You could run your factory DP with the 03-04 exhaust and it should work. Nothing will be gained at all by using an aftermarket 4" DP since that is already what you have.
 
If you want a set of MBRP duals I have one taken off my truck. I went to a 5" single when I put on the twins. I'll let them go really cheap. T304 stainless in really good shape as I wiped them down every 4 months with WD 40. Two polished 5" slash cut tips included. If your interested let me know where your located and I'll take some pics. If not I'll be puting them in the classifieds.
