I have the Bassani and thought it was too loud (nice loud but loud) with or withour tip resonators. Added an inline 4" straight through resonator and now think the sound is perfect..slightly louder than stock, but still deep, no rasp, nil drone. I have the MSDS Y-ppe which is louder than stock but retains stock cat so it is not as loud as catless Y. I "suspect" that with both a catless Y and a resonator, the car would be about as loud as a standard Bassani with stock y (ie no cat and resonator cancel out).. But just an educated guess, I could be wrong..
