I'm quite keen on keeping mine standard looking. I'm actually thinking of doing a modification to the EGR valve that reduces the amount of exhaust that can pass into to their inlet. I'm thinking of turning up a restrictor plug for the exhaust inlet side of the valve that has a 6mm or 8 mm hole through it. This will still allow it to pass a small amount of exhaust gas, but stop it from gooping up the inlet tract.
The idea behind this is to stop the 2K misfire, the is only evident when the EGR is blanked.

A 6mm or 8 mm hole will goop up in no time.
What are the advantages of fitting an EGR bypass over simply blanking it? One is cheap and easy to do, the other more expensive and a sod to get at.

No reason for a 6mm or 8mm hole to goop up. The goop only forms due to the oil mist in the intake system. This oil mist then partially burns in the intake when the hot exhaust is admitted, forming the goopy soot.
There's no goop in the exhaust transfer pipe, so a small hole won't clog up.

Non really. Fitting a bypass does the same job as plugging the vacuum pipe to the EGR valve.
In theory the removal of the valve in the inlet "could" improve throttle response, but it's doubtful anyone would notice.
I'm going to try a restrictor, as I want to solve the 2K misfire riddle.
