Muffler delete - Learnt a lesson the hard way

So I was back in town for the weekend and decided to go get a muffler delete - did that and boy from the moment I left the muffler shop, I was feeling a bit weird - almost like a teenage boy in a decked up honda or a mazda lol.

My wife sat in the car a few hours later and the first statement is - why is this car making a sound like that of a truck! My heart just sank lol. It just confirmed my thoughts as well that it just makes the car sound and feel very teenage'ish and cheap lol.

To each his own but this definitely is not for me! Going right back to the shop tomorrow to get the muffler put back on.

That's funny cause that's exactly what I didn't want to do I have a 328 and wanted the mtech dual number not a fan of the single and was afraid to do straight pipe ended up buying a stock 335is exhuast and used th the mufflers only and I was nerves to turn the car on when it was done but it sounds perfect for me completely stock sounding better then a 328 and a little less then a 335 wife didn't even notice till she asked about the bumber

One thing I noticed was that the sound softened a bit over time. Maybe you should give it a few days/weeks before you put your mufflers back on.

Also I feel that it does affect the pick up of the car - again this is in my opinion and maybe its just in my head now that I am not liking the sound lol. Also I did find it misfire once. I guess you got me thinking now...let's see.

It's more likely that you just got used to the sound. There's not really any structural reason the sound would change.

Its completely age related – trust me – and given the fact that you mentioned “a wife” that tells me you are old enough to have a little less tolerance for loud exhausts (whether they be tin can sounding or throaty) and more importantly “drone” at any consistent speed / nothing wrong with that…but even before I opened your thread and simply read the title – I smiled to myself

I have been debating the muffler delete in my e92 as well. Been listening to youtube clips and the sound isn't too bad but I'm afraid of the drone sound heard inside the car.

I believe only kids who cannot afford to mod their car would delete their muffler.

My muffler delete sounds better than any exhaust setup I have heard.

To the OP, what engine do you have? I have the N52 and my muffler delete droned like no other when I first drove home from the shop. Like you I wanted to drive right back. But I let things settle first and it has broken in nicely over the past 7 months. I even get compliments left and right about the sound. No joke.

I actually decided to get mine done after hearing my friend's 335i with his mufflers deleted. Our cars definitely sounded different and I really couldn't figure out why. I agree that there shouldn't be any structural reasons why the sound would change over time, but it sure feels like it did.

I listened to a lot of youtube videos before I got mine done. IMO, it actually sounds a lot different in person so I wouldn't make your decision just off of youtube videos.

Here is mine. Honestly I hated the rasp in the PE. That exhaust was a joke at 1,000 dollars and others were 500 or more, and since I wanted a dual exhaust I would be hacking it up anyway. I figured I would start with the muffler delete, knowing I could always add a muffler later. But I love it.

Here's a video

That's why you buy a proper exhaust... Of course chopping a muffler off is gonna sound like a "decked out honda"... cause that what they do!

I have the N52 as well and yes, I think the drone inside is what is bothering me. I am going to have my wife drive it past me while I am standing outside and see what the sound is like on the outside. I don't know if I can last the 7 months with the kind of sound I am getting right now lol.

Let's see.

I actually did it after hearing the sound of the car of another forum member on here. I heard it in person and even took a ride in the car to make sure. I liked the way his sounded and he also has a N52 engine. Maybe his sound got better/smoother over the few months like a few others have pointed out here...going to check with him.

Well it only took a few weeks to settle not 7 months haha.

Most of my driving is in the city and it doesn't drone. Only on the highway so if most of my driving was like that then I would probably want a muffler back on as well.

But the sound is amazing outside the car. And there's a ton of burbles/overrun when in DS mode.

They're right when they say that everyone has different opinions. People on here might like it just because of the type of community you're asking. However, the majority of people would likely agree a muffler delete sounds pretty bad.

If you're at all concerned with annoying passengers, neighbors, or anybody else, just get an aftermarket exhaust. They make them for a reason. If you don't care about any of those things and like the sound of the delete, go ahead and do it.

You could also try the Active Autowerke exhaust for the N52's. I personally like the way it sounds quite a bit--very mature. I'd call it an understated, yet quintessentially classic BMW sound.
