996TT Fabspeed Generation 3 Exhaust install
#16
On cold start up the cold start injection kick in and leans the exhaust out to bring it up to temperature rapidly to start burning cleaner emissions. It is a 2 minute process and then the system shuts off and the exhaust mellows back down.

Any Acoustical engineers out there???
