Muffler delete or resonator delete
Hello,
Have anyone done a muffler or resonator delete? How does it sound? And does it drone? Thanks

I took out the resonators, which didn't do much.
We do a trick with the late model Corvette mufflers at my shop. I did the same thing to my 550i, M5 and now my X5 M. I cut a window in the top of the muffler, pulled out all the packing and made a piece of sheet metal that would cover all the perforations in the pipes inside. I tack welded it in place and then heated it so it would conform to the shape of the pipe using a hammer and small chisel. Then I welded it all around and welded up the window I had cut. It sounded pretty good, but still a little too quiet. I took the muffler back off and did the same thing to the bottom of the muffler. Now it sounds really good and has no drone. I get a lot of compliments on it. I put on Akrapovic carbon fiber tips (knockoffs) and it look and sounds as good as anything out there. I think I'm going to put an x pipe where the resonators were just to see.

check out this post https://f15.bimmerpost.com/forums/sh...php?p=25102197 Guy did electric cut-outs. He also tried adding an X pipe. He said x pipe was quieter and didn't sound as good. I have done a few x pipes on NA cars and found that the sound and tone was improved. Maybe not with turbos?? I am either going to do a muffler mod like suggested or e cutouts. E cut-outs will be louder and can control with a separate remote to open/close anytime I want. |

I recently did a Muffler delete only on my 2015 BMW X6M. Love the way it sounds may add in X pipe soon right after mid resonators. I haven’t had time to record good videos but will post link showing a cold start no revs because it was really early and loud lol. Also a short video of a normal start with a couple of revs in normal drive mode. normal start/drive mode cold start |

I did the same, deleted the muffler, left the resonators this time, added an xpipe. Love the sound, it doesn’t drone in M mode, but in the regular non M mode I find there is definitely some drone, but not enough to bother me. The refined sound with the X pipe makes it sound like an exotic car.

Sounds great. The M5 has it stock, not sure why we didn’t get them.

No, because of the rpm’s, shift points etc, it’s obviously much more tame in the other modes and tends to drone. I am hardly ever in those modes though, sometimes when passing police and it I need it at its quietest.

If you did, was it a bypass through coding / a simulator? |

I haven’t had any CEL due to muffler delete yet I just had them unplug from valve and tuck wires. I unplugged it before muffler delete in the past as well, and rode around with valves open and didn’t have a CEL issue so I guess it’s same concept.
