Default 2011 Hatch - Cobb catback gaskets/bolts same as OEM?

My 2011 sti hatchback came with a cobb exhaust. I have the opportunity to buy a 2013 WRX hatchback exhaust with no bolts and gaskets. Does anyone know if I can re-use my gaskets or will I need to buy new ones?

Probably not the gaskets but the most of the bolts should work with the exception being the downpipe to midpipe hardware. I believe Subaru used spring bolts and a donut gasket at that connection that is not used with the 3" exhaust(not positive though because I've never owned a Cobb catback). You will most likely need the OEM donut gasket for the downpipe to midpipe connection, a 2.5" 2 bolt gasket for the midpipe to axleback connection and the OEM spring bolts for the donut gasket connection.

Thanks. It’s also probably worth mentioning that I also have a cobb downpipe.

Found this on cobb’s site

You will reuse the factory spring bolts for the connection between the midpipe and downpipe. You’ll use a donut gasket.

So it looks like the only gaskets I may need is from the mid pipe to the two mufflers which I think should be a smaller diameter.
