Anyone know what the stock exhaust piping size is? I'm going to guess anywhere from 2-2.25" crush bends.

I just took off the stock exhaust a few minutes ago. Pretty sure its 2.25". Also its all mandrel bends.

Can someone tell me if this is good enough to replace my the pipe connected to the Muffler? My muffler fell off. and it broke at the pipe. I just want to straight pipe it from the Exhaust Gasket and remove the broken jagged edge pipe.

If your pipe "is" 2 1/4", (ID or OD?) then you'll need an adapter/reducer to connect the pipe you showed from Summit.

Per my digital caliper, tC2 OE piping is 2.5" (60mm) at the header collector and then tapers down to 2.125" (50mm internal) on average for the rest of the exhaust system.

Most aftermarket kits are 2.25 to 2.5" (60mm internal) and are mandrel bent. Doesn't sound like much difference but 10mm is pretty significant for flow rate. You don't really want to go any bigger on a N/A system anyway. The most restrictive parts of this exhaust are the manifold and axleback/muffler.

Best to make a cone-shaped adapter to fit different pipe-diameters. Better than stepped kind you find everywhere.
