i had a magnaflow muffler. It got annoying within my second day of driving... It was non stop droning when you drive in the 2-3k RPMs. When I roll the windows down, it is so damn loud its hard to hear. I don't know why its so loud. Took it off and sold it. Even my friend got a cheapo exhaust on his RSX and its not loud as the magnaflow. There no drone but the sound from the outside is loud.

Cheapo exhaust, no drone, loud as hell
Magnaflow exhaust, drone, quiet
IMO, the magnaflow sounds good but the loudness inside the car is not very MERCEDES BENZ.

I should have just went with an C36 exhaust or C43, but those are very costly. I regret buying the magnaflow when i could have put money into my suspension.
