How loud?

six-n-twins53 · 12-20-2016, 08:15 AM

Hi guys. Just a quick question about M2 exhaust sound/volume. I am trying to decide if I want an exhaust system or bypass. I don't mind kinda loud, but don't want piss off the neighbors loud. I had an E60 M5 with no mufflers and an STi with an exhaust. The M5 wasn't too bad, but the STi was too loud. I have a 235i now with BMW sport exhaust that is too mild. Does anyone have a frame of reference for me?

Take delivery in February. So I have a little time

Thanks

I'm happy with stock exhaust with catless down pipe. Not too loud and not mild. Everyone taste are different I suggest reaching out to anyone local with M2 to hear their setup

+1 on getting catless downpipe, if not get an exhaust system ... Not a big fan of the muffler bypass

With MPE and flaps open, it's still a lot quieter than the STi I had with catless Downpipe and Borla XR-1. The STi would could hear down the street. The M2 you can only hear pulling into the block. With flaps closed, you can barely hear it a couple of houses away.

That having been said, stock will be even quieter.

I have MPE + Catless DP's + Eventuri Intake and with flaps open and in sport or sport plus it's actually ridiculously loud. Almost to the point of me wanting to put back the catted downpipe on. Thank Goddddddd for the valve control button. I keep it closed most of the time. I open it up once or twice a day and it sounds like a race car and makes me smile then I close it so I don't get complaints in my neighborhood (may be too late already lol)

Stock it sounds nice but I still want it louder. My Bypass arrived yesterday and wil be installed Friday, will try to get some comparo vids but online videos are difficult to properly capture the true sound.

Thanks for the replies. I'll take all the help I can

Could you please give the dimensions of that box ? My daughter is going to be in New York for a few months and I'm wondering if she could fit that exhaust in her suitcase when she comes home.... so avoiding shipment costs and import duty.

I can measure when I get to the shop, they ordered for me so it was shipped directly to them.

DK IF u interested but i use a 3" DP with a 3" exhaust cutout. Used to have an electronic flap by Quicktime peformance...now im running a 3" loud valve. Its a boost activated cutoff that runs open dp stating at 2 psi...for the loud valve you will have to create a boost source tho...

Luckily bc valvetonic you have full boost b4 u thottle body at wot...

pruettfan · 12-28-2016, 05:22 PM

OP, I would wait till you get the car and see if you like the stock exhaust before you plan mods. In my opinion it is a very nicely balanced. Sporty and gets plenty of attention while being very livable day to day.

AYurch · 12-28-2016, 05:57 PM

You will be pleasantly surprised at how loud the stock system is. By no means is it a screamer but it sounds very good. If money was no object I'd get the active Autowerke system as that is in my opinion the best sounding M2 exhaust I've heard to date. That or Dinan which is second up to me.

quikM2 · 12-28-2016, 06:05 PM

Sound is such a subjective thing. I've heard the MPE described as 'quite loud' but to me in reg. sport mode it sounds great and balanced. on cold start its loud but once it warms up and regular driving its quiet to my ears and I only hear it when I step on it. Track mode on the other hand is pure symphony and sounds amazing. Some though would find it obnoxious and not like it.

So basically what I'm saying is listen for yourself as everyone hears things differently.

NO_USER_ · 01-07-2017, 02:22 AM

If you go catless on the M2, do you need a tune because it changes the characteristics of the car? Or because you need to clear the CEL?

I see that there are CEL fixes to go along with the catless downpipes, I'm assuming they aren't using a tuning solution? Is it safe to drive the car catless without a tune? I come from the WRX/STI world, and it's must to have a tune whether it's catted or catless.

Thanks!
