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 in the vid. 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. At part throttle cruise and slight throttle increases, quiet as stock. It requires some load to shine. Nice upgrade that I would do again. |

If you want a deep note, that is pure stock at idle and at part throttle around town, but has more volume 1/3 throttle and up....this is a good system. If you want a louder idle, louder part throttle, louder cruise sound and very loud wot.....this is not it. I bought it to bridge the time until Akra is released in September.....but I do not want a police magnet....I might just keep this system as a cool balance. |

Nice! I’m on the same boat just trying to mess around with it till Akra drops their exhaust system. Not really looking for something super loud just yet. I’m ok with a change while WOT. Does it burble more/louder while at higher RPMs? I will be getting my car back tomorrow so I’m kinda anxious. |
