birish21 Posted May 31, 2016 Share Posted May 31, 2016 I just finished my M4 install and when I went to go run the bike I noticed smoke coming from the right header where it connects to the M4. Any idea what could be causing this? It is clamped tightly. Link to comment Share on other sites More sharing options...
AlbatrossCafe Posted May 31, 2016 Share Posted May 31, 2016 A brand new exhaust will have a small amount of smoke come off of it at first as whatever coatings get on it during manufacture are burned off. My Akra Carbon gave off a small amount of smoke for the first 5 minutes or so that it ran and I thought I had a leak, but it turned out it was perfectly fine. Run it a bit and see if you still have the same problem after a few miles.

I don't see visible smoke like I did before, it sure does smell rich as hell though. Link to comment Share on other sites More sharing options...
AlbatrossCafe Posted May 31, 2016 Share Posted May 31, 2016 Hopefully you can wash that grease off. The rich smell makes sense... you now have a straight-through exhaust which seems to let a lot more "smell" through I have noticed compared to the stock exhausts that I have had. Once the ECU has a chance to recalibrate itself after some miles or you buy a tuner/get an ECU flash some of that smell should fade.

rick Posted June 1, 2016 Share Posted June 1, 2016 No cat converter will allow all sorts of smells get by that weren't there. Is there still an O2 sensor in the system or is that gone as well? Link to comment Share on other sites More sharing options...
Beemer Posted June 2, 2016 Share Posted June 2, 2016 Did you use the pipe sealant that was suppose to be provided with the pipe? That would make a difference, perhaps. Beemer Link to comment Share on other sites More sharing options...
