Anyone know? 4-2-1. H22A. I would just assume eGay, but look at those perfect welds, even in my cell phone pic you can see dimes on dimes.

Any leads are appreciated.

 

I name it Bob.

 

You can see how it comes apart with the flanges on the collector. Thats means its a cheaper ebay header. A H22a performance header usually always have sleeves that slide into each runner. More or less its a stock exhaust, but you could do the 2" collector mod and make it better then it currently is.

Here is a pic of a PLM header, see how it comes apart with sleeves not flanges and gaskets. PLM and Vibrant are probably the two most common cheap"er" power gaining headers. $300-$400 bucks

 

Thanks for the suggestion, but this isn't exactly a budget build, it'd be better to put that toward a Myers.

Good info, I didn't realize ebays usually had the second flange. I will just do the 2" collector for now, I've been wanting to try my hand at it

 

there is likely a rather large difference in material quality and construction between a PLM and vibrant. given a vibrant is made by vibrant with vibrant materials. PLM is made overseas.
