Cold start noise

What makes the exhaust super noisy on cold start up and then go quiet after a short while, it seems to be temperature related, the colder the day the longer it takes.

The ECU does it. It's emissions related. It's meant to warm up the catalytic converters as quickly as possible.

Fordgt40 (and midareff1) doesn't like the loud exhaust, so I don't think he's interested in the Active Sound Module.

With the sound module, you can actually make the car quieter on cold starts, if you so wish.

I certainly do like a loud exhaust, the noisier the better, hence me choosing the PE on my latest one,I’m just a bit dissatisfied with the noise it makes, not sure whether to bother with the ASM or not, I’m not sure how long I’ll keep the car.

Why does Mercedes fit these valves, leave them off and I’m sure we’d all be happy.

I like having the ability to make it quieter also because I use it as a daily driver. I wish I had a ford gt!
