Good to hear that you are pleased with your G56 Stage One kit, particularly after my recommendation. Not cheap but worth the money. You will find the engine is much more responsive and tractable at lower revs now. I know some say it's a no,no but it will pull without hesitation from 2200 rpm in top. Surprised you find it difficult to get the exhaust bobbins in France. Try Renault p/n 7700565762 if you get stuck again, there must be plenty of them?
