Hello everyone, as I've seen that a lot of the members here have akrapovic on their cars and as I'm tempted myself to get it, so I thought you could answer me some questions about it.
1. Does it void the BMW warranty?
2. I'm thinking about getting the evolution system with wireless kit, but not the downpipes, do they make a big difference?
3. With the valves closed how similar is the sound compared with the stock sound? (With the valves open I know it is just brutal
)
4. Did anybody already have any problem because of the exhaust itself? or anything related with it?
5. I read that when you get the exhaust you have to make some changes in the ECU, it this true?
6. Does it affect the fuel consumption?
7. (Stupid question) The wireless kit has any batteries? What if it runs out of it? Easy to change?
I would be very happy to hear your reviews of the exhaust and thanks in advance for you help!!
