Headers for the ZL1?

All of them require trimming the belly pan (no big deal)

All of the good ones are stainless. I have ARH on mine

All of them can be coated, but I don't really see a need.

The 2014 ZL1 and up come with a different belly pan cover and will not require trimming for header installs, you could just buy a newer belly pan to use with your headers and keep the older one if you decide to take off the headers and go back to stock setup in the future.

All available headers will require trimming of the 12-13 belly pans. As RLHMARINES said, the 2014's have a different design that does not require cutting, so that may be an option.

Here is a picture of a belly pan that has been trimmed:


All Top tier headers are made of 304 stainless steel. I recommend going with Kooks.

We also offer coating at an optional/additional cost and have various options.

Feel free to call, PM or email me anytime with questions.

I went with kooks and high flow cats I have a 13 so trimmed the pan to match the '14's

6 hour install on a lift by myself

But would a rotofab intake + Kooks headers + high flow cats, and a pulley require a tune? I know it would benefit. BUT...would it REQUIRE... I'd love to get some more out of the engine but DO NOT want to void the warranty...just yet. So I've got about $1,500...and I can get the headers, cats, and rotofab.... But...I see this pulley stuff....what to do???

I did not think that the SLP headers required any trimming?

I assume you are talking about a lower pulley. Lot's of folks are doing the lower and CAI without a tune. Pretty sure you're OK with the headers as well but if you do tune you'll be looking at injectors to get the full benefits.

I believe if you went with the intake, headers and a 5% lower pulley you would be in a safe area that a tune would not be required. I posted the same question a few months back and if my memory serves me correct, that is what I was told. Torco gas additive may need to be run for spirited driving and if your area does not provide 93 or higher gas.

And what would those be without tuning. Even with tuning headers are one of the best HP gain mods you can do.

the only brand I know that did not require belly trimming is the pfadt and they can only be aquired used. You still might find someone who never installed them on the web though.

I would look at the following I listed them kind of in price order. From what I have read these are all perfect fitment other thant he belly pan which is plastic and the area cut does not affect aero or cooling enought to really worry about.

1. ARH
2. KOOKS
3. STAINLESS WORKS
4 STAINLESS POWER

they all can be coated so that is not an issue.


I went stainless power will install monday they are supposed to fit perfect. some people seem to have issue with not

A. buying all USA MADE
B. not spending over 1k on headers


one reason to spend the extra money if you want 2" tubes and are shooting to the moon power wise. anybody who thinks that extra $500 on headers is money spent in the right place on a modest build like mine is fooling themselves IMO as that 500 towards other mods would make more power. I don't get into the us vs china debate anymore outsourced manufacturing is just the way things work now. If a product has good quality is what I care about.

If I had lofty goals I would have spend the extra coin on kooks or ARH for 2" tubes.

Be careful with the Cats. They don't last long on the ZL1
