I would like to hear what you guys think about 4-1 vs. 4-2-1 Headers on a LS with 404's, Si slugs, and JG ported head. Any one heard of a good or bad header to use with this or simular set up. Also which companys would be best -- I'm thinking DC just cause its like $240

 

search is your friend

 

and your not

 

If your car has a fairly good drop on it go 4-2-1 or you will prob end up smashing yours in like i did to my DC sports 4-1.

 

Yeah I was thinking about that but as of right now I only have H&R Sports So I think I should be Ok. I was thinking it would help me out on the top end and cause the LS has a good Low end I could have both ranges.

 

What are your power goals? Do you want to add more power down low, or at the top of your powerband? You should buy a header with these kinds of questions im mind....

 

Well I did seach and didn't find any info on my set up But as far as What I want I would like to be able to use a 50 shot and have a lot of Top end power. But , I would like to not have to Rev the Sh*t out of the engine to produce power maybe up to 8K.

 

Check out the Kamikaze header im selling ( http://cgi.ebay.com/ebaymotors...29739 ) 4-1 design, 2.5 inch collector and said proven to be great for supercharged and figure would be good too for nitrious, brand new and cheap.!!!
