Yes all the hardware to extend them was included.

I suggested they try to include extended wire with connectors on both ends to make it plug and play no soldering. They just need to find where to buy connectors.

Soldering the wires to extend them adds to the install and could cause issues if not soldered right.

can't thank u enough for the time you're putting in to dyno the headers. hopefully we can find some one to sort out a 3" drive by wire throttlebody and a custom manifold with a better turning neck like what sasha from sg had done before he closed shop

why did they design the steering rod differently for the revup?

i could be wrong but didn't the revup come with electronic tilt for the steering housing for the interior?? possibly why they redesigned the steering column

as far as i know they didn't. i've never seen an 03-04 with electronic tilt. i could be wrong though.

would be nice to have the ppe headers and sg-motorsport headers side by side for comparison in bends.....where which collectors bent earlier or later. the sg headers space was so tight one of the collectors had a dent purposely put in one of the collectors to clear the steering column.

Retune is tomorrow with a new throttle body. I found 2 exhaust leaks and that has been fixed along with my nitrous 125shot.

Hoping for better numbers NA but more importantly I want my lowend to match my previous or more.

Track is Saturday in 40* weather going for 12's NA on street tires if my lowend is back. I will update Saturday night or Sunday with video.

My tilt is manual I think they came out from 04.5 to present.

Here is what my throttle was doing on that dyno run. I know it's not much, but I can't help it's my issue down low. I wish cipher showed it in percent instead of volts.

The voltage stays at 3.9V from 3200-4300 then it goes up to 4V. The power drop is in this range hopefully my new throttle body takes care of this.

Don't know if this is how the throttle works for the 5at it slowly opens to 100%, this is with the uprev tuned throttle control.

Notice the throttle blip to 4V at 4k on cipher and the dyno power went up then back down when it went back to 3.98.

why my track times sucked and yes I was floored. This was worse than the dyno run the voltage was like 2.5V then slowly ramped up.

well the drop is still there don't know if it's because I'm 5at or what. Big thanks to Vince from RT tuning who tried to tune it out and tuned my nitrous.

The car now flys with nitrous, but because of the drop in power the car feels like it bogs then hauls a**.

Because of this issue my launches sucked I have the topend but no lowend now and my throttle is still not opening fully even with the new throttle body.

I don't think this will be a issue with 6mt's who knows it may just be my car.

Here are my nitrous times with a 125shot if my 60fts where better I would of been 11's for sure. My best NA yesterday was 13.3.

of course without nitrous with nitrous it put down 384hp/380tq. The numbers before headers is on page four.

The step on the PPE headers is after the bends while the SG headers step is on the bend not too far from the headers.

The bend on the PPE headers for the 370z has the step like SG.

I don't know why they didn't put in in the same area for the DE. I looked at SG's dynos and they have almost the same lowend drop but it's not as long, but 6mt's and 5at's are dynoed differently.

Just trying to figure out the drop and most exhaust shops told me the LTH give up some lowend for good mid range and top end gains. They also told me since I'm 5at I might need a higher stall converter.
