The new G30 M550i xDrive is without a doubt a very impressive vehicle. If you want near (relatively speaking) M5 levels of power but you aren't quite willing to spend M5 levels om money then this car is definitely your answer. Hell, in terms of acceleration you can even beat an F10 M5 for a good quarter mile or so, this car is no slouch. The unfortunate bit is that in its factory form it just doesn't sound very impressive. The folks at Dinan took that as their cue to develop a sweet new exhaust for the M550i, and use the platform to introduce a new-to-Dinan feature. While the classic Dinan 100% Stainless Steel construction and smooth exhaust tone are still present, they have done away with the welded on single wall exhaust tips. Times are changing and consumers expect exhausts to come with interchangeable exhaust tips. Dinan decided it was time to start moving towards clamp-on dual walled tips so their new exhausts look more modern and give you the ability to change them out if you so choose. Couple that with the 8 horsepower and 6 ft-lb of torque you get (which is impressive for an axle-back) and you have a modern take on the classic Dinan exhaust you can be proud of for years to come.
