Anyone running catless primary with stock secondary’s? Or something similar to the photo attached? Interested in hearing some feedback!
I have the Stone exhaust downpipes with the secondary cats on my car currently. They are insanely high quality and sound better than full catless in my opinion.

Previously I’ve had secondary deletes, and then fullcatless(Evolution Racewerkz) and just didn’t like the exhaust sound.

When I have sometime I’ll start a thread with some pics and quality videos of these downpipes paired with the Dinan x-pipes. This setup sounds really good to me and other M5 owners locally agree. It has turbo spool sounds, louder pops and bangs, but has a better V8 sound signature.

I’ll add some pics shortly.
