Headers for ZL1 - Page 2 - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

Anyone putting headers on may want to buy a spare Belly Pan if you want to convert back to stock. Or buy the "shorty" headers so you don't have to modify the pan.

Do theses have to be tuned like on the SS?

I have a set from my LS3 SS I want to put on the ZL1 the flanges look ok but not sure about the fitment.

help!

The earlier SS Kooks will not fit the ZL1 without modification, and yes they do need to be tuned. The flanges are the same, it is the tubes that are different.

Everything is not the same on the two cars, the primary tubes on the passenger side will hit if using the old SS headers, however the new ZL1 headers will fit any Camaro SS as well as the ZL1 of course.

Also heard that KOOKS is working on a Cat-back exhaust for the ZL1 as we speak.....

Yes you will. This is a car built by Aspire Performance Tuning with complete American Racing exhaust.

Do the ZL1 headers require cutting of the belly pan? I'd like a set of headers that that don't modify part of the car that was specifically designed for ZL1 and essentially be de-engineering the car. What other brands require cutting and which ones don't.

So are the American Racing headers the same for the SS & the ZL1?

Yes they do, as far as I know and have seen all long tube headers require cutting of the belly pan. It's not really in a area that is going to change any of the characteristics of the pan though. The NACA ducts for the transmission are not touched. You just want to make sure whoever is modifying your pan that they do it cleanly.

Shorty headers will not require cutting but they won't give nearly as much gains, if any.

THANKS FOR THE PICS'!!! That's the first that I could easily see that the pans are what looks like fiberglass. I was hoping they weren't plastic or something, but it looks like either fiberglass, or SMC, like older 4th Gen doors and trunks were made of.

I'd like to see what those ARH shorties do, because that's the way I'd have to go...

If I could get away with LTs, I surely would

I used headers designed for SS. I didn't have to modify the pass side at all. The drivers side needed minor clearancing at the steering shaft and at the motor mount area. Took about 10 min to remedy. WOW this car is LOUD LOUD LOUD with long tubes and no cats.......I like it..
