I had the exact one on, it was pretty darn loud. My girlfriend always came out of her house before I got to her house. If you are gonna use it I think you should have it before the muffler, if flows well, but the drone at 2200 RPMs makes it sound like you're lugging your engine and its lacking power. Actually makes the car sound really weak and slow. I upgraded to a Magnaflow 12266 I think, and after about 2000kms it sounds really nice now, maybe I'll go outside tomorrow and record a new rev up for you. Here'* my old thread to refer to for your exact muffler, my fun with having no muffler, and lastly, my current muffler. I will post again tomorrow with another rev up since the current muffler has finally broken in, it puts a nice growl and rumble to the ride.
