The question is why would you buy it at all. It's not a header, it's just a stock manifold that flows slightly more.

To anwser your quesiton, buy the gasket here: (it's a kit)

or JUST the gasket:

Not enough to warrant the cost.

GMPP Header is $285 plus shipping for 2-5-HP

ZZP Header and Downpipe combo starts at $300 10-15 HP.

You do the math.

i bought my GMPP header from CED 2 years ago while it was on sale for $235. it makes a difference. nothing like a header, but it flows better than the stocker for sure.

this one is the most bang for your buck, the stock dp will bolt up and it comes with gaskets and free shipping.
I will be purchasing this next paycheck for sure.

You do the math.

10-15 HP for just a ZZP header is probably being a little generous

There are a few guys on this forum who port the stock manifold. Performs as good as the GMPP.

The GMPP manifold is a good for those who want to maintain their warranty. Also, aftermarket headers increase cabin noise.

Bolting on a GMPP will gain around 5hp. Tuning for one can gain another 10hp.
