I know it's very hard to even see an M2, let alone hear multiple ones with after market exhausts.

I have full Fi Exhaust with catless downpipe, located in Melbourne, let me know if you want a listen, maybe it'll help you decide !

Mate I have the exact problem at the moment and I'm trying to decide between the Fi and the M Performance. You happy with the FI?

How's your ESS tune going?
Any issues so far? CELs?

M Performance for me, is only the name.. It cuts into the OEM exhaust, and you'll probably end up getting a DP, the Fi is obnoxious though, I love it! Quieter than stock with the valves closed under 3,000 RPM.

If you want something ridiculously loud and sounds amazing go with Fi, if your not prepared for either spectrum of the loud to quiet, try getting a free flowing downpipe first, because the stock system is still 3inch.

My ESS tune has now settoed in, and for me, it's perfect, if I didn't know it was tuned, it runs like stock, but extracts more power and is actually 1-1.5L/100km more fuel efficient.

It's dynamic so it constantly gauges by the readings the vehicle is out putting to it.

If you have never driven a stock M2, you would assume it hasn't been tuned, because there is nothing out of the ordinary, no fake exhaust trickery, no anti lag tune, none of that crap, it's a simple replacement of the stock software with software that is more efficient as it does not need to be 200% safe, it's now 1205 safe. For example factory cars all come more rich because it's safer to do so. ESS will lean out the vehicle within the safety parameters to extract more power with more boost, and reduce the fuel consumption.

So when you say the exhaust is obnoxious what exactly do you mean? I love loud exhausts, but are we talking loud through the rev range or like an AK47 going off when you let go of the throttle?

It's both, the off throttle pops are as loud as anything around. It's seriously like gun shots!
And WOT, it's very very loud as well!
