Dinan has released their exhaust for the N63 V8 twin turbo X6. The sound is not over the top yet more aggressive keeping the conservative Dinan approach. The claimed gains are only 7 hp and 6 ft-lbs of torque, no dyno as usual. Not exactly the choice for big power. It is a completely bolt-on application and the tips are ceramic coated black for an aggressive look. Pricing comes in at $3599, check out the video for the sound.
