Default up-pipe & warranty

Would installing a aftermarket cat-less up-pipe void my warranty on the turbo if something were to break in the future?

If what ever part you install is proven to have caused the problem your claim will be denied. It will not void your warranty.

Probably. While I sorta doubt it will harm the turbo, Subaru could argue that the increased exhaust stream caused more stress on the turbo. I also suspect the added heat in the rear cats (they now have to burn more of the left over fuel) would be a reason for Subaru to not pay for their repair. And they could try, in theory, to not allow claims on the entire engine/tranny/drivetrain under the idea that the modified turbo response caused more stress on the entire system.

Having said that, I'm still considering doing it to my car.

As stated above, it depends on what breaks and the circumstances surrounding it. You could always replace it with the stock uppipe if you ever had to bring the car in for service if they give you any hassles. But, on the flip side, you're modifying your, so you shouldn't play if you're not ready to pay.

Just curious, does anyone know if the Japanese spec, Australian spec, or otherwise have 3 cats in their systems? Like ours?

Do all foreign countries have as strict emissions like CARB?

What I'm getting at, is if this same engine & setup is used in other countries where the stock WRX has higher performance, wouldn't it also be due to having fewer cats, well, and probably diff. fuel.

If that was the case, I'd find it hard to believe that Subaru would try to blame an engine failure on removing a CAT, I could see them voiding the emissions warranty though.....

I believe that the JDM spec WRX has only 2 cats and No "precat" in the upipe, and i wouldn't doubt that the remaining cats are less restrictive than ours..
I'm not sure about every country but i know that U.S. standards for emissions are higher than Japan right now..i don't know specifics

3 cats for everyone. That was the whole idea - that this be a "world spec" car.

The emission standards are actually pretty similar - US Tier 1 I believe is a little tighter on cold CO. The 3 cats were also needed for latest EU emissions.

The cat in the up-pipe only improves emissions while cold. Once the car is warm it does much less.
