You are a good to very good mechanic. I am...not.

Do you have HFCS now? With tune it'd be more like 5-10

You might net 2-3 Peak HP yes, but throughout the powerband you gain more. Difference under the curve, that's where they make their money. :tup:

Drivers side sucks because of the steering linkage, once that's tackled the actual install isn't so bad.

Ha thanks. I'm mediocre. Its more my friends are awesome and I'm a Good assistant.lmao im good at putting everythibg down on paper andnknowing how it works. I still have so much to learn physically doing the work.

Unfortunately, I'm not a mechanic and would have to pay someone a ton to install them

Cody, have you had yours tuned yet? Curious what gains you did get?

Me? Well I had the stock Nismo tune. The dealership installed my Stillen G3 intake and then I had it re-tuned once the exhaust and HFCs went on.

Here are the results:

Edit: Oh wait, NM you said Cody.

That dip right in the middle of the page... I wonder what causes that, it's under 5200rpms so its right in the middle of the powerband... Interesting.

VVEL kicking in?? Or that must be where the stock systems restriction started to block flow?

Beats me. That dip was in every pull they ran though. Vanished with the cats/exhaust on the car vOv

Then it's something potentially with flow maybe? It's odd that it does it stock, but not aftermarket, and it affects both power/torque... And it's such a short spike, it's not an extended problem cause it goes back up afterwards...

Well, this car is bitchier than my last Z. I'll just chalk it up to "personality" and be done with it.

:icon17: Don't worry bud, we've all got qwirks... Mine flatlines at 6500 rpms... No reason why yet, just does, makes good power up to 6500, then just stops... :ugh2:

Cody how much do you want for those headers anyway? I feel like I asked you this before but I don't see it in my PMs. You can PM me or reply here, w/e

$1050 and I'll bring um down to a meet personally.Lol $1200 shipped.

Also Chris...I'm on my phone so I don't feel like copy and lasting your post to quote but with just exhaust no tune or intakes...on a stingy mustang dyno I made 291whp and 245 tq. Add 10% and that's what I'd get on other dynos. So more like 320whp 265tq. Add akuma intakes and a tune and I see 340+whp easy

Gotta tell you those numbers are fluffed bud. Don't expect to be that high.
