EL headers make more power everywhere if you select the right ones and get properly tuned for them. There are some out there that are not a good match for the stock turbo. They weigh less and if you wrap them, the under hood temps can be controlled. Not just my .02 but from my experience.

The best header that was ever made for a STU prepped STi was never purchased by anyone unfortunately. Have no idea why no one bought them:

Headers require careful monitoring. I def dont suggest not wrapping them. They get to close to things that will melt or distort. Use the new wraps that dont burn and keep an eye out for oil leaks.

Because its a factory cast manifold clone but stainless. By evening out the exhaust pulses and reducing the turbulence is where you make power. EL is the best and a tubular UEL is second best. Not a fan of the Litespeed thingie

On the header front, I have to say that I am Extremely pleased with my Killer B EL, even on the low end. While it is white lighting coated I feel that there is more heat under the hood, however some of that has to be due to the higher (than stock) power level I am now running.

I am thinking about wrapping them on top of the coating to see if that helps any

I dont quite see your point. Ya its a cast manifold clone but with way better flow than a ported cast mani can ever get. Plus the runners have been increased just enough to produce positive results. That header prob makes more power than a ported mani (dont have back to back data to prove that hence the 'prob') (which we are all agree makes good power) and weighs 17lbs less. Sounds like a win win to me.

Yeah it'll flow better but you're still dealing with the same design issues of the stock manifold. You have 3 areas where two exhaust pulses are coming together. At each bank and at the collector. A true tubular UEL and EL will only have 1 maybe 2.

Just gotta look around and the cars that make really good power are running equal lengths or tubular UEL's. No other car manufacturer or aftermarket company makes unequal exhaust manifolds, evo's, v8's, honda, etc.

Does anyone have relevant results using the standard diameter Perrin or Invidia ELs?

Define standard. The Invidia Race has 42mm primaries. I believe their older version (which includes an integrated uppipe, making install a pain) has 38mm primaries.

I have the Invidia EL Race header. My ASP/DD car has pretty much every bolt-on with the stock turbo, and gained 18whp/43wtq by adding the Invidia and tuning for it. (All on 93)

Several other members have seen similar "insane" torque gains from this header. TopSpeed also saw similar numbers with their 2011 STi test/shop car. You can't beat 400+ wtq @ ~3100 rpm.

Great meeting some of the other names on this forum this weekend. AWESOME STU field, was lots of fun all around. Congrats again to the green-wheeled-wonder drivers.

By "standard," I was referring to the non-big tube headers. I've seen both Perrin and Invidia versions with larger diameter tubing, and I figure that's not ideal for my application.

I'll definitely check out the Invidia Race.

Thanks! Definitely a great weekend! Nice driving on your part as well this weekend. And yes, finally names have faces.

Sorry to jet out of there yesterday. On Austin's last run, the shift linkage/shift fork inside the transmission broke and the car was stuck in 2nd gear. We ran straight back to the paddock, threw the car on a borrowed trailer and dropped it off at TiC. Overall, a rough weekend between the turbo and transmission but some good times! Good meeting Josh and Shane. You can ship me those Rivals anytime

Agreed. It was a great weekend. I finally got to meet some of the folks I'd been chatting with here and on IWSTI. My 1st day didn't go so well, but I'll take the 2nd day.

Good meeting you guys too! I had no idea about the car breaking, that blows. Can't quite catch a break lately.

And I do have a set of Rivals I could sell if someone needed them...for the right price of course.

Nope, he didn't because he didn't think he had a shot. And also because it's hard to sign up.

yeah it was the first part... but is it wrong I am more excited about the 3rd place finish than I am sad about the lack-of-free-tire?

But you could have had both for very minimal effort.

Dude, even this no-talent, bad-habit-ridden, hack driver registers for the contingency.

This. Having a kid will reduce your racing opportunities for a while. I have only autocrossed 5 times since last October. But it will also mean you get to be a carwhore. I've driven 5 different cars in my last 5 events.

Question on fog lights.

So 14.2.C says fog lights can be removed, but what about the fog light cover?? The rule mentions removing other small trim and cosmetic bits.

If it can't be removed can it be replaced with one from a different year?? If I can't take them off completely then I'd at least want ones that look decent after the lights are removed. Thanks.

I have the OEM optional fog light covers, but not the fog lights. The pass side fog light hole has a duct on it going to my stock air box.
