huh wierd about the resonator... but I should be able to post a sound clip this weekend. I have the resonator on my car. If someone without it wants to post a sound clip of theirs, then we would know for sure...

but I was just watching a few vids on youtube of other cars with and without the resonators. It completely changes the sound. It gets a little louder, but its not as smooth. In low rpm's giving it a little gas, my car is LOUD and its SMOOTH. sounds great... all of my friends that ride in my car complement the sound. If I were you, I'd install it with resonator and drive it around for a bit. If you don't like the sound, get the resonator removed. It probably comes down to a matter of personal choice...
