the flapper mod, thats no more than disabling the diaphragm on the back of the exhaust dude
its there for EU noise regulations to keep the car quiet at low revs, once you build the revs the diaphram opens and the car runs at normal noise levels, by disabling it you'll only get a minor increase in noise levels (same as when your at higher revs) so kinda pointless although will crack a small smile but no where near as large a smile as an aftermarket replacement imho :happy2:
been there, done it :innocent:
Hedge:
The flapper only appears to shut off one of the exhaust exits which is why one pipe is always cleaner than the other.
Res Milltek ftw or Capristo if you're feeling rich. :evilgrin:

I appreciate its partly to do with noise but if you read into it, it's also to help with exhaust gas velocity which equates to back pressure which results in a little more torque at low RPM. I'm going to disconnect and block it off and see how I get on.
