Im ln the market for some headers, I have a 96 blazer 4.3

Ive been looking at these from ebay and they say only 97-01 blazer, but then says ALL 4.3 models

Stainless Manifold Header Exhaust 96 01 Chevy S10 Blazer GMC Sonoma 4 3L V6 OHV | eBay

What is the difference? the other set they have is like $600

 

I noticed those are for vehicles with air injection

 

Check Summit. If yer just looking for headers they have a pretty good selection. I put a set of "Summit" brand headers on my 5.7 and the tag on em says Pace Setter, but they are cheaper than the ones in the box with the same name. Just a thought, easier to deal with if there's a problem vs ebay (I am an ebay user btw) plus free shipping on anything over $99....

 

Do headers really make a difference in the 4.3?

 

Yuo can around 14 more horse IF you have your computer updated (flashed?) after they`re installed. You would also need dual exhaust and high flow cat and muffler. One more thing, use header wrap and give them as much space as you can, they get hot

 

I'd like to put a pair of headers on my 05
Blazer to help it breath and sound better
It's an everyday truck will I run into any
Problems with running a pair of shortys
And my stock exhaust?
