Hey Flavio, I have the same setup as you. I was at Ktec this morning speaking to Adam. They have a replacement part planned to have a bigger silencer up front, but not dead sure when its coming in. I am like you... its way too loud! I have only had the car a few weeks, its for track but to drive any distance I am using my noise cancelling headphones plus I sound like a Mcdonalds car park champion everywhere I go. I am going to look into a replacement silencer myself in the meantime, Ill keep you posted. Any plans yourself?
I dont know if there is anything straight swap in terms of parts or a silencer I can buy and have welded in to replace the existing one but I will see. New to Clio's so need to get under the car and have a snoop around.
