BMW F30 328i Borla Exhaust Startup

Borla Cat-Back Exhaust startup and revs. 2012 BMW 328i Sportline. It has the 2.0 turbo motor rated at 240hp and 255tq from BMW. Dynos have it closer to 268hp and 285tq. This has the Stage 1 JB Tune good for ~310hp and 330tq (at the motor). Factory stock times are 0-60 in 5.4 with the Tune dropping it to 4.9 based on testing. The only missing factor is a decent exhaust note. Burger Tuning Info here: I’ve used Borla twice on a C5 and C6 Corvette and
