Thanks gents. top tips!

Hi all and sorry if this has been asked before. After 2 years of hunting I finally have somewhere to keep a Caterham so am on the lookout for a 420R. While it will be mainly road use, I want to do some club track days (to hopefully learn to drive thing rather than thinking I can!). Some of the cars I have found have RBTBs fitted. Does anyone know if this will cause a track day noise problem over a standard 420R? Thanks in advance.
