+1 on the Bassani. Its got a nice mild rumble at idle (much less than 90db) but sounds great when you get on it. When the Polizei are near by you only have to upshift to quite it down. Thats harder to do with the flowmaster type baffled mufflers that are lound all the time. You need to combine it with a Bassanni XPipe with converters to get the full cool throaty sound effect. You will also improve your torque/power throughout the rpm range. Bassannis are one of the top systems for power increase. But since exhaust sounds are very subjective, I recommend you listen to sound clips online (youtube etc.) before you buy anything. Thats what I did before buying the complete Bassanni BX system.
