BMW F82 M4 High Flow Downpipes & Stage 1 ECU Software!

Today we have fabricated custom downpipes to this BMW M4 and tuned it with our Pop & Bang ECU Software!
Our custom downpipes are more free flowing than standard resulting in more power gains and a more aggressive exhaust note!
With this package you can increase the power by 70bhp over stock and gain a staggering 130nm of torque!
This system still uses the stock valves so if you need it to be quiet you can do that easily with a click of a button.
⚠️Please note, before any remapping work on the S55 engines we strongly advise having the crank hub fix carried out to avoid failure.
