so just upgraded my pfl for a fl.

First thing i notice was the lack of exhaust drama, only the gunshot on up shifts when my foot is down.

No burbles or popping from overrun or downshifts - im pretty sure the exhaust button does nothing.

Anyone experienced this before?

Thanks
I also upgraded from the pfl and posted the exact same post on here when I did, it’s really annoying isn’t it but it definitely makes less noise on the fl!

I removed the resonator and it adds a little bit extra noise but not much (might even all be in my head seen as the resonator was so small anyway)
Is there sound deadening? I am going to talk to dealer because it’s night and day difference. I only get the upshift noise.

How was res delete with warranty?

It seems like it’s an ECU thing? No pop and bang map...
I have removed all resonators from my exhaust and it’s under warranty nobody has even mentioned it. Just been in for warranty work as well as cam shaft sensor failed causing a massive miss fire so I would say it warranty safe imo. Obviously voids exhaust warranty claims !

Thanks for the reply, I have booked it in to Mercedes for a look and health check. Then remove the res!

Okay this is a good example:

In race mode, my perf exhaust does not make these crackle noises when hot. I’m getting it booked in to see what’s up.

My PFL was a machine gun compared to the FL!
