I had on on the Nissan pickup I used to have. V6 3.0 with 40 series Flowmaster through 2.25 tubes. There was a noticeable performance gain over stock. The truck would rumble at lower rpms but was never loud when driving at speed. Was not rice sounding at all. The truck seemed to gain most of the power from the muffler near the top end around 3500-5000 it also seemed to pickup in throttle response in comparison to stock, revs would rise and drop faster. Torque also in increased, when in 4low wheeling I no longer had to worry about stalling as much as before.
Back pressure in the right amount = torque. If your exhaust is to free flowing you gain lose it off the bottom end and put it at the top. That is why I stuck to the 2.24 tube and 40 series for a more overall pickup.
The muffler is tough as nails, super heavy gauge steel with fully welded construction. Fully backed with a warranty to I believe.
