F10 M5 OEM exhaust mod.

[-Z-]

Right, I love the car but it could do with more volume pootling round at low revs with the windows down.

On the V8 M3 you could cut a flap on the upper surface of the back boxes, sleeve the perforated pipes within and then have it sounding amazing for £300.

Bonus was stock appearance kept and no one could tell visually unless you took off the exhaust.

Anyone tried this on the F10?

This is our exhaust cut open:



I'm guessing under the wool on the right side are perforated pipes which could be sleeved?

I still want to give this a go if it's reversible?

Hence maybe cutting out the perforated pipes may be better so come the end of my lease I can weld back in the originals.

At least it looks like only a small window at the back of the box needs to be cut so very stealthy.
