Default Header Dyno Comparison

does anyone have any dyno charts showing the real difference between uneven length and even length headers?

i've heard many subaru's driving down the street, with that unique sound.

personally, i dont care about it in the slightest. i want what will give the best power gains for my investment. if it happens to be uneven length, so be it.

but, i'm curious if anyone has actually done any sort of comparison.

thanks!

You guys can do a search. There's one big one with dyno comparisons a few years back. Yes, I know having other being your personal google is easier...


BTW EL gives around 10hp in the midrange to redline, UEL like 4hp or something like that.

Gagen (joltdudeuc) posted his dyno chart comparing Borlas to OBX EL in the last thread we fought about this subject.

Gagens dyno showed 10 hp over the UEL at peak power, around 4800 RPM I think.

This was just posted last week.

Out of sheer principle, no. I said search, I searched for it myself and 6 pages of threads since 2003 or so showed up. You got dyno charts from everything from OBX, Cobbs, and MRT EL headers.

Like I said, be your own google
