Unequal Length Header

[CB7Nub]

I was looking for some information on a unequal length header for our cars. Mainly on a F22A or H22A. Of course it will give you a nice rumble. But I heard it would increase low end power. Not sure really sure as mostly Subaru's run this.

Any ideas for unequal length headers on a F22A/H22A N/A application?

Subies run UEL headers on their turbo cars because that is how they designed the stock manifold. This is also only for their turbo manifolds, where header design is not as critical for making power. A UEL on a naturally aspirated inline 4 doesn't make much sense.

But correct me if im wrong there would be variances in the cars intial speeds at first.yo and way off topic but lmao..at the signature wth the quote about free food can i copy tht

this one is custom made by a member in washington.
it has better primaries, 4-1 collector and a bigger downpipe. it improves torque but not so much on hp. it sounds a little rumbly.

Intresting Design and I actually would like to get my hands on a set of these. I like having Mid range power vs High range power...

Aren't equal-length headers better for turbo applications, for smoother flow?
