Doug Thorley long tube headers facts, graphs,pics and video

[Doug Thorley Headers]

JBA headers vs. Doug Thorley Headers. Which is Better?

See post 67 for an explanation. Moving the 02 makes the ecu think that the rear cat is actually the front cat.

How do the long tubes do with a cat-back, cold air, and tuned with a UniChip??

Well I got in from work today. Climbed underneath the beast and did it. Although for my O2 simulator I didn't' solder the wires I used the clips that cut through the sheathing. Works great. Now no check engine lights. Just power. But man you need small hands to move around underneath. I got pinched a few times but it is so worth it now.

Don't know much relating the dyno to performance expectations and results for the truck too well! Seeing that the HP is up nearly across the entire band, does this mean that the truck will get off the line quicker and how much quicker will it complete the 1/4 mile?

I completed the 1/4 mile in 14.71 with my crewmax. I have the TRD CAI, Rear Swaybar, and Borla Dual Catback 2-1-2. The Unichip goes on in the next couple days. I am hoping that the Unichip will knock off .2 to .5 and then wanting to know how much the DT long tubes will knock off if added. Of course, I will have to send my Unichip back to get mapped for the headers.........
