Im booked to have a cat-back exhaust from KTR and David told me they are now substantially quieter as they have fitted new baffles etc. I was going to go for Magnex at first until they said theye didnt have a cat-back for a 172Mk2 or cup. I am still a bit concerned that the "quiet" K-tec is going to sound like a rally car, and I need your advice urgently!! Ideally Im after a discreet burble to 3000 revs and not too wooried about the noise level above 3000 when I floor it, although it should comply with 85dB track day noise restrictions.
Cheers, Phil
