  1. E90/E91/E92/E93 (2006 - 2013)
    Hello. Yesterday i was trying to force a DPF regen with the carly tester and app. This time i couldnt get it start, haven't tried that before. I noticed in my live data moniter it said the "exhaust gas temperature" was 1 degree celsius. Could this be the reason the regeneration will not start...
  2. F85 X5 M and F86 X6 M (2016 - Current)
    Just looking to get some clarification from those out there. If I am getting a 180001 and 180101 code, is it for the upstream or downstream O2 sensor. Also, does it make sense to have to change out O2 sensors with a vehicle that has 40k miles and a stage 1 BM3 tune?
  3. X3 F25 (2011 - 2017)
    Hi everyone, Please do listen to the noise on the video. The car is driving fine and nothing wrong with it. There is this sound that you can hear while in the car which is driving me MAD! It's constant humming almost like "wooooohhh" sound near the exhaust somewhere. Happen when car is cold...
  4. E82 / E87 / E88 / F20 1 Series (2008 - 2014)
    Hi, my 2012 bmw e82 throws fault code 2766 DME: catalytic converter 2 current. In the code listing it says it is "Camshaft sensor input: signal duration". According to a specialized mechanic it is necessary to change the catalytic converter but my question is this solution real or is it...
  5. E63 / E64 6 Series (2004 - 2010)
    NB: Keep your opinions about legality and ecology to yourself. This thread is not a request for your opinion on emissions or loud noises. Thanks! I want to go catless. In my country it’s not really feasible to order catless headers unless you’re a billionaire. I want to cut the cats off and...
  6. E60 / E61 (2004 - 2010)
    I have been looking for the loudest possible exhaust. I have all my upgrades just siting in my house, fbo fueling pure stg 2 turbos, I have all done all the maintenance now all I am waiting on is the exhaust. I don't really want to put all these mods in and have a week ass exhaust. Any ideas...
  7. M3 & M4
    Hi all, I've got the stock M4 Exhaust system - BMW M4 2017. The noise is great when accelerating, pops and bangs like it should, however I'd like a little more noise. I don't want anything too crazy, maybe another 30% louds and more pops. What's the best option for me, without making the...
  8. F30 / F31 / F32 / F33 / F34 / F36 (2012 - current)
    I had my BMW F34 GT 2015, inspected yesterday and they said I have a leak from the flex pipe. I've been searching around for a way to replace it and as far as I know, the only option is to weld it back on? Or are there clamps for it? Is there anything else I need to replace when replacing the...
  9. E36/7 Z3 (1996-2002)
    About a year ago I purchased a 50k mi. 1999 2.8 z3 roadster (5-speed) and I love almost everything about the car except for the sound. It really just sounds like a big vacuum cleaner until you get past 4k RPM and you can barely start to hear the engine but even then it sounds meh. I don't want...
  10. E60 / E61 (2004 - 2010)
    2008 528i N52 As the title says I'm interested in making my exhaust a bit louder than it currently is. About 5 months ago I went ahead and did a muffler delete. Have to say was shocked how just removing the muffler made it Pop and Burble. Love how it sounds as well. After a few months of...
  11. G20 (2019 - Current)
    Hi Everyone! My friend recently helped with the development of Valvetronic Designs' new G20 330i system and currently has the prototype installed on his car. I'm definitely a fan of the sound but I wanted to hear everyone's thoughts!
  12. 5 Series
    eyequest2010 member: 1021664"] I have a beautiful 2017 G30 xdrive performance package with RaceChip Booster MST cold air intake and M Performance exhaust. It runs like a dream. Minimum mods with head turning results. Dahler makes a flap control device that's plug and play right into the...
  13. F30 / F31 / F32 / F33 / F34 / F36 (2012 - current)
    Hey everyone. I got my hands on a take off muffler from a 2014 435i (PN: 18307646997), complete with the flap/valve.. It seems like a direct fit on my 2017 430i (obviously with a different diffuser) Can anyone confirm fitment? I know the year-correct retro-fit part should be from a 2017 440i...

  15. X3 E83 (2004 - 2010)
    I'm looking to find a catless down and mid pipe for the 2.5i N52 engine on the 2004 BMW X3, are there any other BMW models that use the same engine, style of exhaust piping, and set up that I would be able to use the catless aftermarket part for?
  16. F80/F82/F83 M3 and M4 (2015 - 2019)
    hey! Long time scanner but new member. My 2016 M3 has had an annoying rattle for a few months. Looks to be a crack in the rear muffler. Tried to get it welded and was unsuccessful…apparently when I told the muffler shop it was titanium, he didn’t believe me but “tried his best”. The rattle...
  17. X5 G05 (2019 - Current)
    I have been pondering about doing this since I ordered the car in December '21. 6 months forward, I have deleted the factory resonator and the sports exhaust in the back. Even with the flaps open thru bimmerlink, there was not much of a sound that matched the 8-cylinder engine under the hood...
