Cool video comparison of unequal and equal length headers!

Never understood why people would want to kill the boxer rumble.. Performance gain isn’t that big and makes the car sound like a honda imo.

Lol Gabz, coming to the dark side now, so soon after getting an S2000? :P

So to sum it up
Unequal length: more BRAAP BRAAP
Equal lenghth: less BRAAP BRAAP

Much much cleaner sound with equal length.

here’s one showing them both under load https://www.youtube.com/watch?v=B6j94LkYo60

Subaru !!!

Unequal length FTW !

Here’s the word you’re all looking for: sonorous.
What a beautiful sound!

equal length just removes the boxer rumble, you might as well buy an inline 4

equal length and bigger pipe!
