The well known Steven Dinan is no extended aspect of the tuning corporation of the similar title (he now owns and operates CarBahn) but it still places out some of the ideal tuning elements for BMWs on the sector. For the BMW X5 M and X6 M, Dinan now presents a new exhaust procedure that enhances their V8’s sound, even though also including a couple of horsepowers.
No one’s ever likely to accuse either the BMW X5 M or X6 M of being slow. Their 4.4-liter twin-turbocharged V8 would make 617 horsepower in Competitors-spec and 553 lb-ft of torque. That allows the two SUVs get from -60 mph in under 4 seconds. And when that is interesting, there is 1 quite regular complaint amid enthusiasts—noise. The S63 motor is strong, refined, and pleasant to use but it’s by no means sounded specifically good. Even in the BMW M5 CS, the most enjoyable car or truck to use the V8, it under no circumstances sounded unique. Which is in which Dinan comes in.
There are a couple of various configurations of the exhaust you can get: the axle-back again, the x-pipe-only, and the whole procedure. Each and every configuration appears drastically much better than stock, as confirmed by the video place out by Dinan. Naturally, the most excessive variation of the exhaust is the full process. It’s the loudest and most aggressive but even the whole system is refined enough to be driven each day. Even so, if you want a subtler, far more refined growl, you can just adhere with the axle-back again setup. Although, the full-beans configuration adds six horsepower and 5 lb-ft.
As with most modern-day aftermarket exhausts, it is a valved procedure, which can open up and near, to make it louder or quieter, based mostly on the settings in the car. So if you push the exhaust button, just like on the stock X5 M or X6 M, the Dinan exhaust will adjust its tune accordingly. Dinan also promises that the process has “drone abatement” technologies to retain cabin resonance down, regardless of valve location. So it should not be much too annoying to hear from inside the vehicle.
Clients will get a alternative of two unique exhaust recommendations: double-walled polished stainless metal or black ceramic coated. Either way, the tips evaluate 4.5-inches in diameter.
Dinan has often designed great exhaust setups for BMWs, specially for V8s, and that hasn’t adjusted. At the moment, only the axle-again setup is available for sale, with a price tag of $2,499.95, regardless of which exhaust idea is selected.
