Dyno complete

Loving the low end torque increase with these! Its hard to see on the graphs 'cause they don't go that low, but you definitely feel it. Exhaust note is awesome too. Sorry about the video quality, but you can still hear it. Overall very very satisfied with my purchase.

For the runs:
Same dyno, 5 days apart, same gas (92octane)
My truck is almost completely stock; just TRD S/C and a borla muffler. So I'm sure there is plenty of restriction in the intake and y-pipe (not for long!). The ONLY difference here is the headers. Best of 3x runs for both days.




Thanks for puttin the graph together Gadget!

We have shipped a good many of these header sets now and have had two reports of an installation issue that I want to give everyone the heads up on.

We have had two customers that have reported that the have had their starter cables come into contact with the headers and melt through enough to cause a short.

Those that are installing the new Spec-U headers please make sure that your starter cables are not in contact with the headers.

Those that have already installed your headers, you should take a look and make sure yours are OK or if the starter cables need to be clearanced a bit.

Mine were touching. I noticed it after the first drive though was smoking a little. Put a zip it around them and solved the touching.

is there any tests between the DTLTs and these URD LTs? I'd be interested in getting them if I saw the comparison between the two

 

[Gadget]

I am not aware of any direct comparison.

Looks like you would be in a good position to take care of that!!

Can u get these headers in a natural stainless. I'd like the have plan stainless instead of coated. I gotta cut off the flange anyway and put a v band on it or can u hook me up with a v band already done g man.

It will be released when I am completely happy with it.

So what are the odds that you will have an equal length Y-pipe that will fit the 4x4's?
