To give you some more data :
0 dB gain at idle
0 dB gain at 2000 rpm hold (basically, a high idle)
6dB gain with stationary throttle blips.
WOT under load is the best improvement.
If I rated the Factory Base stock exhaust a 0
The Akra on my X5M a 8
I'd give the Competition Exhaust a 4 or 5. Definitely worth doing, definitely enjoyable. If you like it LOUD LOUD wait for a race muffler.
