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 :)

 

I have one. Maybe 5-8hp at the most

 

cool, i ordered one, putting in hopefully tuesday

 

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???

 

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

 

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

 

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.

 

Oh, I tried that but missed the full site !
