Main cats are the same. The length of the DP you have could differ from the stock DP with precat, and then the extension to the main cat.

Yes, catalytics are different turbo versus non-turbo.

The main cats are different part numbers from the factory, but are the same dimensions so they are interchangeable. Most aftermarket cats are listed by the same number for the N/A and Turbo.
