This one for example is on a 228i using a Stock M135i. Sounds very good. The best setup I ever heard was on a 228i with a 335/435i M performance muffler. It sounded amazing but I can't find the link. Here is the link to the 1st mod I was referring to; http://www.2addicts.com/forums/showthread.php?t=1032968

Going to try this. Anyone know how easy it is to put a new OEM muffler on at lease turn in? By that I mean can you clamp on the modified one without actually doing a weld and then take it right off and put the OEM one back on with a proper weld?
Results will be posted once done. I am planning on taking out all of the dampening material and sealing all the holes. I have the mppk as well and I haven't found a video with this combination. |

Sorry to bring back an old thread, but I have been looking into doing this mod. I've seen all the videos for this mod but I just want to hear this mod in person. I have taken the wire out of my exhaust once, and my parents were complaining about the drone noise and vibration the car had in highway speeds every time I tapped on the gas. Will I run into that similar issue if I do this mod? I won't be driving the car as much anymore because i dorm in college and the car will be sitting at home. My mom or dad might take it out once in a while and I just don't want them to complain about it.
Thanks in advance Last edited by redbullfan; 10-03-2015 at 06:23 PM.. |

As far as the drone by just doing that mod there will be none. If you want to do the actual gutting of the muffler like I did, there will be a significant change in exhaust note. Not so much drone but it will be louder. If your parents don't like it now, they will definitely not like that because of the noise. But it's your car who gives a hoot what anyone thinks lol What are you trying to accomplish? Louder tone but subtle.

Modding the stock muffler requires a lot of cutting and welding. It will never look stock again. Your folks may notice. If you do the muffler mod and leave the golf tee mod stock there really should be no drone. The drone mainly comes from when that thing is wide open all the time. I have a downpipe and there is definitely a nice drone. Not too bad however for me. I can also control the exhaust valve and not have to do the golf tee mod via JB4. When I close the valve it almost sounds stock.

The sputtering is related to something else going on with the vehicle. Does he have any other mods?

But I can assure you that you can remove your whole muffler and other than getting a loud noise with drone it wouldn't change your car and make it sputter. Your back pressure will be different and one can even argue better for the turbo at WOT. Simply plugging perforated holes that are designed to dissipate sound surely won't change your car to the point of sputtering. You start messing with spark plugs, o2 sensors, fuel trim now we're talking drivability issues. Something else is at play here. I know I couple other people did this with no issues. What I would advise you is if you have doubts don't do it.

Sorry to bring back an old thread, but just had a quick question. Would it be possible to just take all of the padding material out while the muffler is still on the car? My exhaust shop wants $350 for the job which i think is absolutely ridiculous considering that i got the exhaust for $100. Thanks!

Against this thread's advice i had a muffler delete done. It sounds nice at WOT but at idle when the car hasn't warmed up fully, it sounds awful. Like rattling the interior loud.
I'm wondering if instead of going back to the stock muffler and modifying it, I could just add a Helmholtz resonator to the piping in the rear to achieve a somewhat similar effect? That's essentially what modifying the OEM muffler does right? |
