AC Schnitzer exhaust
I'm newbie and seeking for your advice for my 2012 335i coupe. (E92-LCI)
1) I like to replace stock exhaust system (right after the down-pipe all the way to the tip) with the Akrapovic Evo SS system. Which this mod, is the Check Engine Light (Service Engine Soon...) will turn ON ?
2) I also thinking to go with AC Schnitzer exhaust, is this better than Akrapovic SS in term of performance?
Thank you so much.
