It's definitely deeper, but I haven't heard it from outside the car yet (if you know what I mean - so it's hard to tell!)

The OEM 1M axle back that Stu installed on his 135i (120d) has been modified.
It has had the baffles removed and the canister internals redirected.
I installed this unit on my 1M some time ago, hooked up to the N55 mids.
It was actually quieter than my OEM unmodified axle back.. I removed it after a couple of hours, so I can understand why Stu is not 100% happy with the exhaust tone.
The quad install and mod on the other hand is awesome and if I had a 135i, would do this in a heart beat as it looks awesome and OEM.
