right now i have a no name short ram intake and a dc-4-1 header with sp2 exhaust. i recently installed cams and a chipped ecu from phearable. my next step is to tune it but i dont really want to tune it with that header and intake with a stock cat. need some inputs. i want to avoid swapping those out after i tune my car.

 

3'' intake
toda header

 

My buddy has a nice Vibrant header for a b16, made a huge difference when he swaped it out. And for my intake manifold i took it to a machine shop and had them bore it out so it still looks stock.

 

is vibrant a ebay header? i heard of that somewhere. any dyno sheets? is it a 2.5 collector? and dood, any 3 in short ram intake? thats what i have now.

not an ebay company

 

Or if you can get your hands on a JDM ITR, that'll be good too. Or the replica made by Street Imports.

 

do the street import headers make good numbers.. i like the price of it. are the welds strong?

I think I've heard them putting decent numbers. The welds look ok but not spectacular. They might have a fitment issue where you need to drill out one of the header bolt holes out a little. Price is cheap. Basically you get what you pay for

think about throwing a velocity stack on it

there are header threads galore.
