Own a 2000 Jeep grand cherokee 4.7L v8, with full three inch exhuast from the Y-pipe back, high flow cat and previously a Flowmaster 70. I was looking for something louder than the 70 but not annoyingly loud. The 40 has a very nice deep sound yet isn't a drumming noise on the inside of the vehicle when travelling on the highway. Aggressive and deep sound when you want it to be, yet mellow enough to not drive you and your passengers crazy. Excellent muffler.
