I would suggest that you install the Bassani first and drive the car around for a month before gutting any cats. Bassani is pretty loud & it drones on the highway - I installed an inline 4" resonator with mine (nice!). Gutting either cat or precats will make car loud and both will be very loud, so make sure you want more sound before you do it.
