So yea.. sound great at idle and awesome at 6000RPM. Pretty plain sounding otherwise.
Liberty or Legacy?

+1 on this, what little rumble my old sr20det had was turned into a terrible sound at wot, all my grunt gone. I'd expect the change would be more vast to the subbie exhaust sound

I've heard the Killer B ELH with a Q300 in person. They sound very good. I will be adding those to my ride when I do my turbo swap next month.

Even with the ELH, makes a barp barp barp barp noise when at idle. The high compression helps with that though I guess.

"sound of ineffiency"...I thought I heard the last of that crap 5 years ago.

It's been shown on the dyno that EL vs UEL makes no real difference. It's all academic...theoretical. In the real world, the gains come from the drop in restriction and increase in flow linearity that comes from reducing the step at the head output and the tiny restrictive ports on the stock header. Stock vs aftermarket makes a big difference, but whether that aftermarket header is UEL or EL doesn't really matter. If anybody would like to dispute that claim, I would love to see the evidence, because an all-encompassing header shootout was already performed several years ago that shed light on the reality of the situation. The only thing that has changed since that test was the introduction of the KB EL header, which may be a godsend, I don't know.

The fact is, if you like the EL sound, then go for it. If you hate the EL sound, then get an aftermarket UEL header, the resulting power gain is pretty much the same.

on a stage 2 car, sure.

on a higher hp car, probably a larger difference than the stage 2 car. In fact, it's been proven in the proven power bragging before. Somewhat recently even.

Here's an old vid I just uploaded. We'll soon have a comparison to our own cat-back, but this is what I've got for now and seems to be a popular combination. The cat tends to quiet it down and cat-less versions tend to sound more rally car like in post 8.
