Hello Mario,
The exhaust, along with the Bluemels wheel were what sold the car to me originally. My car was delayed, and delayed again whilst the factory were waiting for the improved spec exhausts to come through. I had only rumour of the various issues the cars were suffering to go on.
You can see how first reading Peter Dron's superb book, and as a consequence finding this forum has been such an eye-opener.
We can all suffer/enjoy the agonies/ecstasies together.
Enjoy #33...... and good luck with those exhausts.
