Hello, We installed ours on 02 Xterra. Cat back exhaust order from CALMINI.

Bolts right up,less than an hour,NO need to get truck off the ground. Only thing had to drop the spare to side the old exhaust out.

Calmini's exhuast is NOT that loud. (wife's car). It was perfect.

If you want the SOUNDS? ...Take a look at the Flow master 40 or 50 models(mufflers). Just my thoughts here! .......Aloha
