i did a search and found some info but nothing on howmuch it would cost. Im probly gona be getting a greddy header 4-2-1 header and doing what most othe r people did, make the collector 2.5" . also any other info / tips on this would be appreciated

also is there anything else that should/could be modified?

 

Why dont you wait a couple of months and wait to see the headers that Myself, K20EG and Jeff from IB will be putting out there. Theres going to be 2 versions of the H header available so far... A street/strip SS 4-2-1 H header and a Drag 4-1 Side Exit header... $650-$700'ish in full SS

You seriously have to extensively modify your average DC or whatever header too much for it to work somewhere close to your ProSpeed/AN-R/SMSP headers outthere.

The primaries are too small, the transitions suck, the collectors suck... Its not worth it

 

ya i know id have to modify a the thing a shitload but im sure itll end up being cheeper than the top notch headers in the end. plus i dont have the cash right now and im not a patient guy

 

are you going to be using a 2.5inch collector? or will it be compatible with say.. an apexi n1? if it would be.. and gains are good i can get you 3 buyers including myself right now.

 

Yes, the collectors for the Street/Strip headers will be 2.5 ID, THe headers are in the prototyping stages and will not be sold untill we announce their availability along with the revealing of dyno charts.

So hold on for just a little while longer and all your Q's will be answered

 

your header sounds good, but again, im not a patient guy lol.

can anyone else give me any info on modyfying a header?
