Sup guys...
I have a goal of about 200 hp (not sure yet if n/a or boost... it depends on the HPTuner software's success to unlock the n/a potential of our cars), so I figured 2.5" is the way to go for my exhaust. The problem is finding a header with a 2.5" collector because if I'm not mistaking, the pacesetter and weapon-r/rksport ones are all 2.25". Since an exhaust is only as efficient as its smallest piping, I think I would pretty much nullify the potential of having a 2.5" exhaust over a 2.25" if I went with a 2.25" collector.
Is their a way to make the collector bigger or something ? Or do I have to get a header custom made (which I would really like not having to do) ?

all cool mang
most of the 2.4 and eco headers though are usually 2.5 and above from what i remember...
the 2.2 ohv are usually 2.25 and 2.5
They ususually throw a 2.25" downpipe on 'em tho, easy enough to grab a piece of flex pipe and weld a 2.5 downpipe on it.
