I've been wondering what does it exactly consist of to make unequal length headers (in our case, header) for a straight-four. I know subies come with these stock due to design.

I like how unequal length headers sound on any car, be it 4,6,8 cyl engines... it's just not tinny and tends to resonate less. It's a sweeter, cleaner sound. So I'm all UEL Header just for the sound.

I know there is a certain science behind it, but what exactly would it involve to have this done in our celicas?

Ever seen a ramhorn turbo manifold? Im assuming youd have to base it somewhat on that. Being cyl. 2 and 3 runners have either upward or outward turn in then to compisate for how far out 1 and 4 are. Then into a collector.
