How to make stock exhaust louder?

Just got this 09 e90 m3 and seems like all the mods are very expensive. I kind of like the stock exhaust, but it's definitely not loud enough. Not much experienced with exhausts. I was wondering if there were any way I could make the stock exhaust louder, which would also sound nicer as well. any suggestions ?

Sure. You can put any xpipe or ypipe to stock muffler. M3 can gain much power with cattles y pipe and also xpipe

If you go on YouTube and search "2015 mustang GT m3 rev" my video should be the first one. I'd post the link but I'm on mobile and the video is somewhere on this forum.

You shouldn't rule out the OEM exhaust mod unless you want a really loud screamer. The OEM exhaust mod is the perfect balance between casual driving (with light grunt like the stock exhaust) and nice screaming when pushing it. And best of all: it's much cheaper in comparison. But that's just my opinion

Here are three videos of my mod, maybe it'll help you make your decision:



(i love the downshift rev matches! especially the one from 3rd to 2nd in that video...)

(crappy audio, this one's filmed in a tight garage though, so it doesn't really sound like that when you're driving through town but nevertheless it's awesome )

And here's a longer video, from different positions and different scenarios on an open field:

I also like the OEM mod. I get requests from other M3 owners all the time to have the mod done to their cars. If this mod didn't impress, I doubt I would've been asked to assist so often.

I'm no exhaust expert so someone else should probably chime in but as far as I know test pipes etc. would add drone to the modded exhaust. I think not just the modded exhaust, but most exhausts in general. Supposedly it's very hard to find an M3 exhaust that does not drone, even the M Performance exhaust drones, regardless of x-pipes or not.
But I think pipes would make the modded exhaust really loud. You could've done the "hard" exhaust mod (most people have the "medium", some the "soft"), it's supposed to be pretty loud as well
