Duramax Headers

We have hard recorded data showing all gains useing the TxChristopher up pipes and headers. It's all spelled out on DP and the diesel spot that was posted previously in post #4. I was going to start a whole thread on this here, just haven't had a chance.
Data shows high hp/torque gains down low (as much as 100 lt/ft torque at 2000 rpm) for the towing guy like me and an overall increase in power up top (15hp/30 lb/ft), all while decreasing EGT's by 100* and actually lowering ECTs by as much as 5* while towing Not to mention the lack of turbo lag and the overall throttle response is increadible, less tranny downshifts when towing, more available power down low in the towing RPMs....... it goes on and on.
Some say they will crack over time, I don't know, haven't seen any proof of it under normal use conditions. What I do know is the guy who is actually makeing them has been making custom headers for years and I'm sure be knows what he is doing. Some have a bone to pick with the guy, so he will never be right no matter what he does. I do know this, if you want different materials to be used (since you know better than others) bellows instead of slip joints, etc. It can all be done, the price just goes up. These particular type of headers and pipes are for the guy who wants that extra punch, better performance and lower EGTs all without changing programming or having to modify the attaching points (just like a cat back exhaust that requires 'no cuting or drilling'). This is no different than adding a free flowing intake or muffler/cat delete. Remove old parts, go in with the new.

Probably. If I could keep my foot out of it. It's too much fun playing with the boost guage now.

I bet they make a big difference.
Also how about performance coatings? i.e. Jet-Hot, or ceramic.
