Rear cat delete?
Going with the MBRP cat back. Any advantage to getting rid of rear cats while I'm at it?

Deleting the 2nd cats give it a slightly deeper tone, I did it and resold the cats which almost covered the entire cast of the shop deleting them and welding in new pipes

The exhaust system will flow better without the secondary cats, better flow, more power. It may be minimal, but still more HP.

Here’s a comparison between stock, secondary cat delete and mbrp axleback. Definitely a deeper tone and quite a bit more pops.
