does any 1 kno if the stock header on a b16a will fit a 2.5 inch straight pipe??? im taken the cat out.. already have a 2.5inch catback on it
 
shouldnt be to loud i stilll have the stock exhaust welded on but when vtec pops idk might get a lil loud
 
Look for DC Sports' "JDM" header. It has a 2.5" outlet on it. I have one on my Civic. Any of the high end custom headers can be configured with one too.

Want my DC?

you never want to go from 3" to 2.5 on a turbo'd setup. you can go from 2.5 to 3" you can go from smaller to bigger but you dont want to go bigger to smaller. with a turbo you want it to be as free flowing as possible.
