Exclamation Need help quick, Might need to return order!

I made the mistake of buying Tsudo catback for my 2011 2.5i hatch, before i realized that this pipe will get rid of my rear Cat. I googled for a couple hours now and I can not find out if the 2011 2.5i hatch has a sensor on it.

There are plenty of videos of 2010-2011 hatches with the Tsudo catback working.

So quick questions so that i can cancel my order before its to late.

Does a 2011 2.5i Hatch have o2 sensors on the Rear Cat?
Will I be able to use this exhaust with some sort of mod?

Thanks for help, i Will continue top google for couple more hours before I send an email to cancel my order.

Even if you need to lose an o2 sensor, there are ways (tune, resistor) around any problems that will come from it.

I might be retarded, but is the thing in the center of the car a resonator.... and the rear cat is right behind the engine bay?

I shamed myself.

They are both cats. My guess is that Subaru didn't change the exhaust setup. The 2009-2010 should work with your 2011. A 2012, I would be worried. For you, I think you'll be okay.
