Tried to research this but can't find any conclusive answere on whether the above mod would provide more noise while looking standard still... I love my car but the sound is just a little lacking sometimes, i don't really want to go custom as i wouldn't like extra drone, just more of that straight 6 sound which doesn't really come out say for instance like an r32 does.
I realise the hangers will need to change but thats fine as could maybe get hold of the exhaust for £100ish.
Anyone after a 135i backbox? I'm probably not going to use it now, it in very good nick with all the piping to the mid section flange. Drop me a PM [emoji106]

I got some drone after the res delete...but with the 135i backbox the drone was gone and the sound is great...loud when on the pedal and silent when at constant speed!...
Perfect mod..only cost me 150,- or so inclusive the welding etc etc by an exhaust shop...
