I’m in the market for an S2 (currently agonising between N/A and S - the research continues!) and have come across an N/A that has the Lotus Stage 2 exhaust fitted. The current owner has tracked the car (i.e. it passes noise tests) which I was a bit surprised by, as I’d understood the Stage 2 to be very loud and not really track-suitable? What’s the experience of owners on here with the Stage 2?
