Dynotech Headers Installed
Well this weekend I pulled off my stock manifolds, cats, & Y-pipe and installed a set from Dynotech. The difference these headers made in my truck is second only to the blower. I really didn't expect to feel the difference in torque but its there from idle to red line.

How much did your Dynatech headers cost you and where did you get them..?

I got them used from a guy who put a 4v 5.4 in his truck. There jet hot coated to. $500. I couldn't resist.
The A/F ratio is fine. I spoke with Mike Troyer and he said no retune would be required. However I am headed to see him shortly for some fuel pumps, a smaller pulley, and retune. |
Do those headers bolt up to factory y pipe? I was thinking of adding them unless keeping the stock y pipe and cats would make it pointless
|
No. They are long tube headers. You will need to order the high flow cats and y-pipe. This system will bolt up to whatever aftermarket system you have or your stock muffler.
|
Have you cranked out some 0-60 times or anything yet?
|
Not yet. As soon as we have a decent weekend I'll take it to the track again. I want some solid runs with the headers before I up the boost and change the fuel pumps. I want to see how much they improve my 13.55
|
intresting, the roush claims a 13.5 for the nitemare. your trucks a little heavier but should be faster with 427 rwhp and 468lb/ft trq
