    Product Details

    Free Flow™ 304 SS Axle-Back Exhaust System with Split Rear Exit (D660-0067) by Dinan®. Maximum performance gains are 6 horsepower and 5 ft-lbs of torque. Exhaust System Type: Axle-Back. Exhaust Tubing Material: 304 SS. Exhaust System Sound: Moderate. The Dinan exhaust system provides maximum flow characteristics for optimum power gains while producing a civilized, yet very sporty exhaust note that is appropriately aggressive at wide open throttle. And there's none of that irritating low rpm ''drone'' that is common with so many aftermarket mufflers. The mufflers are manufactured from 100% 304 stainless steel inside and out for maximum resistance to corrosion and nearly a 30% reduction in weight, eliminating over 20 lbs. Utilizing the factory brackets and hangers, the Dinan exhaust mounts in a factory-like fashion for a perfect fit and clean installation.

    Not Worth
    This free flow exhaust system is very pad choice. The original one I have in my car have more aggressive sound than Dinan exhaust. Not use fixing the exhaust.

    Difficult Install
    Looks great after labor intensive custom pipe configuration. Website listed this model to fit 2005 330 CI but was not easy. Exhaust pipes didn't match up. Install was pricey.

    Sound of this exhaust system is amazing. No problems with installation process. I would recommend to any BMW owner Dinan exhaust upgrades. It gives a very nice look to my car, also a lot more power, i'm very excited with purchase.
