Yeah diamond eye makes downpipe for the LLY's and LBZ's. The only option for the LB7's is more spendy and includes frontpipe as well as a relocated dipstick from TTS for $671 TTS Power Systems
If you're gonna spend that much you might as well save for an aftermarket turbo IMO
Moto Blue also makes one for the 03-07 for about $270 or so
You might have to piece it together to get aftermarket exhaust from the turbo back unless you go through TTS

I know that removing my cat and going to a stright pipe is a good idea. But the downpipe from the turbo can only flow so much. The downpipes suck to remove (about 2 hours). But still.
Ya for what gain you'll get (if any) its not really worth it. I know people have done a kit like the TTS one thats listed and it takes several hours and some bruised knuckles to remove

The only reason you would replace your trubo down pipe is if you are makin huge power, the D-Max will blow out up pipes and the down pipe, but it takes huge amounts of power.

I learned something new today! I just know when I talked to a lot of people, they said most don't make em because it doesn't help much. I just know that after putting my turbo back system on and removing the CAT...it made a WORLD of difference...

I changed mine and the stock one looks like crap for flow compared to the new Diamond Eye. It is a bit of a fight to get it out but after seeing it I would do it again. I don't know how much a difference it makes due to I changed it and the BD Exhaust manifold at the same time but with the down pipe, manifold and straight piped exhaust I am seeing a solid 300+deg EGT drop. Flow out is heat out. I think Big Red had some pictures on another post showing the difference.
