Hopefully someone here has some input on this

but I currently have the stock header from a supercharged cobalt on my 2.2L and was wondering if anyone knows the specs or have done any testing to see if the shorty header from ZZP has any more gains ?
link: ZZPerformance - Ecotec Shorty Header #ZZ-ECTSHDR

I sent an email to ZZP and they say it has a lot more gain, but I am just wondering if they are just tryin to up-sell?

if anyone has an info on this, be greatly appreciated :)

Gonna order one myself soon. Skyline would you be able to take some pics of the install? Also, what exhaust are you using? The stock dp and catback or an aftermarket unit?

Nrvous1 take a look at Skyline26's signature for his exhaust set up!!
Hey, Skyline26, you still have the MAGNAFLOW cat back system for sale???

nrvous1

Thanks oldblue.. I'm using the chevyhhr app and it doesn't show the signatures. I'll switch to the full site.

Oldblue

There's an app? I've always gone full site!

nrvous1

My mistake oldblue..I meant to say the mobile site. Its kind of limited though, but I use it often when I'm running around and want to browse the forums.

Oldblue

Oh, I tried that but missed the full site !
