M3 Exhaust 16/12/2014 Chucked the Actioncam on the back of the M3 the other day and recorded the exhaust. Standard exhaust, cats have been replaced with resonators. No O2 sensors, so running a bit rich. Has a hearty rasp, thats for sure! 0 0 votes Article Rating Share this: Share on Facebook (Opens in new window) Facebook Share on Threads (Opens in new window) Threads Share on Mastodon (Opens in new window) Mastodon Related Categories:Blog Review BMWExhaustM3 Previous Post E36 M3 Heater Valve Next Post Useless info for the day – E39 M5 S62B50 Oil System
