Competition Werkes Exhaust 2020 R3

Must keep Lambda. Closed loop mode will self correct. Open loop , mostly low rpm, will be a tad leaner. This could effect rideability Probably not hurt engine
 
Oh. The 2.5l wasnt listed when i checked last time. Even more expensive than the werkes ones, guess they are taking advantage of the market.
At least with the Platt you see where your money went, beyond a Y-piece and two mufflers..
 
Is the Dave platt a full exhaust or slip ons?
