I have had my Mini about a month. A 2018 MCS. I did the Dinan Elite and catback system a week ago on a car that had about 230 miles. I got this car to be my daily but drive several Porsches also during the week, I say this for reference. I have a Macan GTS, Porsche 930 and a GT3 arriving to replace my 2017 GT4.

After the Dinan install the car really transformed. It's quick and seems to be getting quicker by the day. I replaced my run flats with real tires and I can pretty much melt them at will. The 25-70 push is as fast as my Macan GTS. Overall drivability is fine, you can control most of it with the throttle and exhaust sounds pretty good too. While I prefer Porsche sport exhaust this was not bad for under 500 dollars.

No issues, no CEL's no nothing. Just instant kick in the pants for not much money. I got it on sale at the same time as the exhaust for 720 dollars. Coming from the Porsche world this is the bargain of the century.
