M Performance Titanium exhaust rattle?

Mccarlin · 08-19-2022, 10:41 AM

Hey Guys,
Recently picked up a 2019 Competition and the car was built with the upgraded Titanium exhaust.
Cold starts its LOUD but also has some sort of raspy or rattling noise. Once the idle goes down to normal it goes away.
Then in some low rpm gears i can hear the rattle again. Is this normal with a titanium exhaust? Exhaust valve lose?
Exhaust doesnt seem to be lose or hitting anything it shouldnt.

If it's anything like this, it's normal.

Doesn't sound normal, might be the connections are not tight or the pipe touching the heat shield in the middle.
