I joined the ///M family a couple of weeks ago and I have to say I am impressed. When I was looking for a car I wanted one with either stock exhaust or muffler delete already done because I knew right away that the car was too quiet. I ended up with a great buy, but not the exhaust setup I wanted. It currently has everything stock except for a supersprint x-pipe replacing the stock resonators. The car is barely louder than what I have heard stock and not close to muffler delete loud. My question to the community is what is the best way to go from here? I see two options that seem logical. The first is a custom setup similar to this...https://www.youtube.com/watch?v=ulVUBnAubBU
I also think that the FMU axelback resonators are a good idea but would end up $1000 usd more than the custom job. https://www.youtube.com/watch?v=iTrXwdHLVHI

I do realize I am opening up a can of worms here, but if you were to pick between these two videos what would it be and if you think there is something better just leave a comment.

Thanks

Seeing that you already have an x-pipe, I think a muffler delete might get too loud. I have heard an e39 M5 with both resonator and muffler delete (with stock headers) and didnt like it. Sounded too much like a Ford V8 and I could tell the interior drone was probably pretty bad.

FMU would be costly, and while its subjective, I think they look very odd they way they are shaped and hang off the rear of the e39.

You already have a great x-pipe, so why not build off of it? If I were in your position, I might consider going with Burns Stainless Mufflers and simply adding them in post x-pipe.

Watch this video for a reference:

For a while, I had stock headers and cats, x-pipe and muffler delete, but I also had magnaflow resonators after the x-pipe. The sound was was perfection, but pretty loud.

All you would need is some tips (I, and others have used Vibrant 1331 or Timmay Tips) and two of the magnaflow resonators (part # 10416).

Here's a quick clip.

I just checked out Burns and I liked the sound in the video. They seem to have fair pricing, but it says its 3 inch inlet/outlet diameter for the exact part in the video. That doesn't match up perfectly to our stock piping does it? Isn't the m5 smaller like 2.25in?

I think that is just a little too loud, but maybe it is just the echo from the video. I could probably find something that knocks the db's down a little more, but I do agree that the sound quality is great.

I was referring to threepedals' post. I don't know if quick reply notifies you of my message or not. Sorry for the noob problems.
Do people have to quote a comment in order for someone to know who they are referring to?

I am in the market for an M5 and have been doing a lot of research over the past year and a half...I am looking for a factory exhaust setup on my future car and I am thinking I will add electric exhaust cutouts just before the mufflers to have that sound of a muffler delete ONLY WHEN I WANT IT. The nice thing about it is the fact that when you want to be stealth, (like late at night for an undercover booty call, lol) just flip a switch. I saw some threads on this somewhere as well as videos on you tube. It looks awesome!

Just my 2 cents on the subject. Enjoy your car!
