Ive heard it on an NA car and its loud with test-pipes-but so are 95% of the systems with test-pipes. Ive also hear it on a TN car and it was very deep, and of course not as loud but still had that very exotic tone.

 

Our new Medalion Touring exhaust system is one of the quietest systems that we currently produce. It may be ideal for you if you are looking for a quieter system. It's currently rated around 91db on a stock 350Z.

Anyone have clips of the Amuse with TN yet?
