Default PRO rules updated, IS2 now matches STX

They might not be 100% the same, but they are little closer anyway!

2.5.2 Headers may be added. 
Modification, removal or replacement of the exhaust from the catalytic converter back is allowed.

Do they also have an exclusion list with the STi and the EVO on it?

STi is inelligible for IS2, 2.0L is the limit for Forced Induction cars.
Dunno about the Evo yet.

I'm really surprised by Jeff Browns response:

"I'll write a cat letter as well, but will ask them to only apply it to the NA cars or not change the rule at all. It benefits the forced induction cars much more than the NA guys and with all the other stuff they can do, we'll still be at a disadvantage if they allow aftermarket cats for all."

Seriously, I think it balances pretty well. Headers can give a Type-R more power and they don't do crap on a WRX. Exhaust changes can free up power on a WRX. The fuel and timing can be fixed on both, but probably helps a WRX more because the Type-R comes pretty bleading edge from the factory. I'm thinking the only real disadvantage for the Type-R in STX compared to a WRX will be the 245 tires that they most likely can not fit, but then again the WRX is 3000+ lbs.

I think we, as WRX owners, understand what an ITR is capable of. It's been around long enough and proven itself (DS, and STX champs and runners-up in 2002) that we know what our target is.
I think the NA guys are just afraid that we'll blow them away with any added power mods since they're still unfamiliar with our cars.
I can honsetly see where they come from, but they don't seem to be as informed as they should be. My car will have it's doors and seat open to them this season. I think a run or two behind the wheel of a WRX may quiet the anti-turbo sentiment a little.

How much HP gain can a turbo car get with an aftermarket "high flow" cat? I would imagine it's no more than an NA car with header(s), cat and exhaust.

I had a response in that thread... then deleted it. It would be just bickering and nothing toward the solution.

My door will be open also, like yours. Heck, I just bought a unichip... winter modding has begun.

And the difference between N/A headers and Turbo headers I understand are a little different due to the boost lag issue. Or is it headers just aren't any good for low end no matter the engine?

I'm thinking about headers, but on a turbo car, they'd be more of a hinderance around low power sweepers waiting FOREVER for the boost to get back up to a usable range... just a larger volume of air to move where a N/A head just evacuates.

Now on a drag car... yeah header all the way on a turbo.

Why else would somebody buy a crusty F Body without a 350?

And you thought GS last year had a lot of different cars! Wait until you see the variance in STX this season.

I think the stock headers are the way to go for us. The only advantage IMO is weight savings. I do know that Kiko has some Cusco headers on his car now......
