To buy headers or not?

Yeah the time & money into quality headers for minimal gains over my existing mods isn’t worth it for me.

It already has full cat back and test pipes and is plenty loud / noticeable gains for me. If I was going to pickup the gains I did when I installed test pipes in addition to existing mods. Then cool.

But if it’s gonna be just a few HP I think I’ll just skip that. I already have all suspension components I want (Tanabe Coils with stiffer swift springs, upgraded sway bars, bushings, end links and camber / toe arms and bolts) she handles like she’s on rails. And I don’t rag on my car enough to upgrade cooling and my stock sport package gearing is just fine for me.

Honestly that was the last bolt on I was considering. My last 370z I had the NST pulley kit on and I liked how much faster it revved. But I honestly don’t think I’ll be installing headers or pulley kit on this one. And those were the last 2 performance based mods I was considering. Maybe a super charger if I can find a good used one for a good deal.

Also halfway considering going air ride. But very indecisive on it.

I made great power with Mortordyne LTH, but it’s a bitch to install idk if it’s any different on a 370 but at least my g37.

Doing the motor mounts on mine and may need to remove the exhaust manifold. Debating on doing headers since the work is already done for the most part. However, HP/Cost is not good. To make any real power, supercharger or turbo is the way to go.

I’m new to this platform and I am interested in the horsepower per dollar topic. Of course the answer to “is it worth it” and “what should I do” is dependent on the owner’s goals with the car among several other things, but I’m curious about what modifications make the most improvement in power.

From what I’ve read, a good 3” long tube intake system and a tune are a must along with maybe a solid, free-flowing catback and mid pipes, but what would be the best next step? Headers can range from $800-$2,000 plus labor, but some have said horsepower gain is minimal so would it be best to invest in maybe E85 and/or ported intake manifolds etc?

I’m all about horsepower and having a good sounding car, but I also want to give some attention to suspension and handling. Don’t see FI in my future with this car, but I do want to add bolt ons and other things that would make this car even more enjoyable to drive
