Thanks for you answers mate! Got to check with the dealer first then, btw what does the downpipes do? it changes the sound that much? I guess the Evolution system is cat-less so I guess the engine check light will appear.

2. if i were you i'd take the downpipe as well, regretting not purchasing and re-ordering will take much more time..
3. dont know but yes, heard them on the track the other day.. its loud.. but having 5 1Ms with akrapovic seems a bit boring *somehow.. its too popular
4. -
5. what cause the engine check is usually the cat-less downpipe, but what my dealer said if there is an engine check. just restart the car and it will be gone *not sure..
6. i do think so..
7. i had valvetronic, it is powered from the car's electronic..

well thats my answers..
