GO with the FULL RDSPORT system... you'll get big gain in power... =)

thats my option:

BMW - Akrapovic

For biggest power gain, get evosport headers + ecu remap. For most aggressive sound, get Kreissieg exhaust system. Rdsport exhaust system + ecu remap probably give you a sporty exhaust note with some gain in hp/tq

thank you so much .. I love the kresissieng exhaust system.. but the power is important.. do you think the rd gonna sound better than the EVOsoprt exhaust system and headers.. I listen yo some of the clips of the rd full exhaust system and its not that good..
