Which catted DP you've got? Did it throw a CEL?
How load is the cold start?
I heard you can disable the cold start noise. Did any of you guys do it?
Mine was a VRSF (https://www.vr-speed.com/vrsf-4-5-ca...0i-xdrive.html)
Yes, I disabled the cold start cat heating in Bootmod3. Nice and gentle on startup now, no worries about noise. I reckon it's actually quieter than stock standard B58. If you leave the heating enabled it's naturally a fair bit louder but not obnoxious or anything. Easily configurable.

If you do disable the cold start, it takes the engine a bit longer to come up to temp (probably 3-4 min. extra), so probably something to keep in mind if you like waking up and going full throttle straight away .
Sweet. Thanks.
I was looking at VRSF catted DP. It's only 200 cell so for sure I need a tune alongside it.
I don't think I will disable it, specially during winter in Canada; but it's always good to know there is the option.

I'm gonna put the order and hopefully I'll get it early next year.
