X5M with no muffler video
Found an old video of when I was getting exhaust work done and took a video of a cold start with the muffler chopped off. Just straight pipes with stock downpipes.

So need to hurry up and do my muffler delete to compliment the catless DP's.

I used these for my guidance.
Mind you the M5 still has stock downpipes, but they have something we don't have...an x-pipe for more depth.

Cold idle was fairly loud stock, so it's definitely louder being catless. Sounds kinda like mine now, so I can assume it's going to get louder soon after the muffler delete.
I asked my tuner to shut off cold idle in the tune, but he didn't and said it caused cold idle jumpiness. Nevertheless I'm going to ask yet again and if I don't like it, I cam flash back to Stage 2 tune that still has cold idle.
