Muffler Delete or midpipe mod on Lease?
Hey guys I have was thinking of doing a muffler delete on my G20 330i but I'm weighing all the options as of rn. The issue is that my car is on a lease and I don't know whether I'll be able to put my muffler back once the lease period is over. Some of my friends were just disassembling the midpipe I'm their cars and putting a washer in so nothing would go through the resonator or muffler and it'd be easy to put back. The issue is that I don't know whether that's bad for the car and I don't know if the muffler delete would negatively affect the performance and durability of the car. Also, with the G20 having a valved exhaust idk if it'd run a code or check engine light. Lmk ur guys thoughts.
Thanks |

Copied from my response to on a different thread. AWE is supposed to release theirs end of fall or beginning of winter if you can wait. They tend to have a deeper tone! They're supposedly going to be doing a touring axleback with a midpipe option. Hoping for a price point around $1,250-$1,500.

I would recommend against cutting the exhaust for leased cars. instead get a full catback system

Did a muffler delete this past weekend on my 330i. Makes a world of difference with the burbles being more pronounced and overall deeper tone from the exhaust. Depends on the dealer but most don't bother to look below the car when turning in after the lease.

I did a muffler delete/axleback and custom-made this past Thursday for my 330e at an exhaust-shop.
He did replace it with two much smaller mufflers so it's not really a muffler-delete but those mufflers don't do much imo. While yes it's a little bit louder, the drone/resonance is TERRIBLE. At 2500 - 3500RPM it's seriously unbearable. I'm usually not so picky or not like I can't tolerate a little drone but this is seriously bad. Very bad... I highly recomend anyone to NOT do this. I had my seats down on my motorway home to fit the stock muffler and with the seats down it was just killer. In a very bad way... This is not BMW, it sounds like crap. Not sure what to do.. I guess we need to find another solution to not have that really bad drone, anyone has suggestions? Either we continue building to find the right sweetspot or I'm just reverting back to stock. Feels a little boring to go back to stock and have done nothing though. All I wanted was a little more sound, not a undrive-able car at those rpm's. As it's not only on motorway that's pronounced but also in city.. This is what it looks like and sounds like at idle/revving. Not too terrible there, but once put some load it's a different story. edit: sorry I can't upload a video, no idea how to do that.. I'm a newbie at forums and attachments doesn't seem to work with .MOV file. Question: Does anyone know what that muffler is in the middle of the car? Is that a second cat? OPF filter? resonator? We didn't touch that one as we were unsure of what it is.. |

Just now recorded one below. Am I crazy or is it so that an exhaust can change after a little while, I kind of feel like the drone is not crazy anymore? Still a little annoying but not insane like it was before/first ride.. https://www.youtube.com/watch?v=lHuIWW-YZaY |

That big thing in the middle is the OPF(GPF)+Resonator. Those small mufflers you have now, what size are they? |

Me too. Also wondering if it throws up any ghost errors or a CEL or anything.

Nice. The think in the middle is OPF with sensor. If removed, it will generate error code due to different pressure. I like your deep sound (although mostly in the lower rpm for some reason). It seems you kept original resonator and replaced big muffler with 3 small ones. I'll get straight pipe from OPF in 3 weeks. If not enough sporty then Cool Air Intake with Turbo high flow inlet pipe will follow. This car is too quiet. My wife asked me if it is an electric car

I've gotten both a muffler delete and resonator delete. The resonator does have what looks to be some form of a secondary cat inside it but there were no error codes once it was off.

Since I got both resonator and muffler deleted in the same time I cannot give you the answer. You can check my Instagram (Misko_Hryzko) where I uploaded videos before and after. Compare it to yours. |
