Putzing around it's quieter than the stocker. At idle it's very quiet but it lets you know something's up. It gives a nice burble when getting on it, yes. It's less throaty than the stocker though... more "crackly". And I swear the turbo whine is slightly audible in the exhaust. It's slight but you can hear it if you listen for it with the windows down.
It's hard to explain, but it makes the engine sound more like a high strung 4 cylinder and less like a wannabe beefy 6 cylinder. It doesn't sound like a swarm of angry bees, it just sounds sporty the way a 2.3L 4 cylinder can.
I think the car should have sounded like this stock. It's a much more satisfying sound.
I purchased it from the mighty Ken of Protegegarage. I PM'd him to see if they had it in stock, they did, so I ordered it. I believe it can be purchased directly from Racing Beat as well.
