NEW RELEASE: Dinan S1 F87 M2 -- Exhaust, Intake and Tune
Featured on BIMMERPOST.com The new M2 has been poked, prodded, and assessed into oblivion over the first couple months of its release. To no ones surprise it has passed all of these tests with glowing reviews and has been labelled the "rebirth of the ///M brand". Customers and publications alike glow about how seemingly perfect the car is. They are not alone in that assessment and we here at Dinan find the M2 a marvelous car as well... but its still not perfect. Dinan has set its sights on improving this already iconic vehicle and wishes to unveil to the world the first iteration of the new and improved M2; the Dinan S1 M2. Complete with a dizzying array of modifications to improve performance, sound, and looks the Dinan modified M2 is a spectacle to behold and more importantly, experience. The entries below provide more in depth details on each of the major modifications that have been completed thus far. A completely new and improved M2 experience is just a few clicks away. Dinan F87 M2 Free Flow Exhaust Part Number: D660-0056-BLK Applications: 2016+ F87 M2 Coupe Photos: Additional product photos will be posted/available next week. Release Date: Friday, August 26th, 2016. Description: The aggressiveness of a track exhaust and the refinement expected of a daily driver, all wrapped into one is what many desire but find hard to acquire. This 'white whale' of a product just became easier to locate with Dinan's M2 Free Flow exhaust system that utilizes the factory exhaust valve in concert with Dinan's muffler design to allow for this Jekyll and Hyde ability. Dinan's Free Flow exhaust system features 100% stainless steel construction measured to exact specifications to ensure proper fit via factory hangers and mounting points. Dyno tuned for maximum exhaust flow with minimum back pressure, this system is designed to provide a more aggressive sound under acceleration, while reducing drone inside the vehicle. This is accomplished thanks to a computer controlled valve that limits noise during low speed driving and opens fully during high-load conditions to allow free flow. For maximum enjoyment and sound when the valve is opened on the M2 exhaust the system becomes a straight pipe to achieve peak power, flow and tone. No matter if the valve is open or closed the exhaust gasses make their exit via Dinan's signature enlarged, laser engraved, black ceramic quad tips. Not only will your M2 sound breathtaking, it will look the part as well. Benefits of the Dinan Free Flow Exhaust for the BMW F87 M2:
Dinan Resonator Delete Kit for the BMW F87 M2 Part Number: D660-0059 Applications: 2016+ F87 M2 Coupe Release Date: Today, August 19th, 2016. Description: For those that wish to have a bit more volume out of the system we offer a kit in addition to the axle back exhaust system that makes removing the factory resonator a breeze. The Dinan Resonator Delete Kit for the for the F87 M2 allows for an aggressive tone to be achieved out of the stock system as well, but coupled with the associated Dinan exhaust the sound is further perfected into an aggressive growl that is hard to ignore. This piece removes the factory resonated section and replaces it with straight-through 3.25" T304 stainless steel tubing for better flow, and sound. Please Note: The Dinan Resonator Delete Kit for the F87 M2 is only confirmed to fit with the Dinan Free Flow Axle Back and stock exhaust systems. Fitment with other axle back units is not guaranteed. Dinan F87 M2 Carbon Fiber Intake Part Number: D760-0038 Applications: 2016+ F87 M2 Coupe Release Date: Today, August 19th, 2016. Description: Efficiency and maximizing the potential of the stock intake design were the keys to development for this N55 intake on the M2. Our sealed system delivers as much cold outside air as possible to the engine via an optimized carbon fiber tube that mimics the stock pipe but with less resistance with a straighter freer flowing design. The increased amount of air feeds into a larger volume airbox complete with a larger filter that elicits a sporty tone that makes the intake sound as good as it performs. This optimized design yields an incredible 8HP and 6 lb-ft of torque even without any additional modifications. Simply perform the short bolt-on installation in under an hour and enjoy a more powerful and audibly satisfying driving experience. Benefits of the Dinan Carbon Fiber High Flow Air Intake for the F87 M2:
Please Note: The Dinan Carbon Fiber Cold Air Intake for the F87 M2 requires modification of the drivers side strut brace. Dinan is developing carbon fiber replacement strut braces that will not require this modification as an alternative and will be sold separately. Unfortunately this option is months away from a retail release. Dinan F87 M2 DINANTRONICS Stage 1 Part Number: D440-0049-ST1 Applications: 2016+ F87 M2 Coupe Release Date: Today, August 19th, 2016. Description: The backbone of any tuned setup is the engine tune itself which allows optimization of boost, air, fuel, and lambda targets among other variables. These specific parameters allow the car to safely extract as much power as possible out of the engine. On the M2 this task is especially daunting given how close to the edge of its capability the N55 and its turbo are tuned from the factory. BMW did not leave a lot on the table to work with in terms of additional power output as the turbos are taxed heavily out of the gate. In fact, in its stock configuration, the M2 is nearly the equivalent of a Dinan stage 3 tuned M235i (the stage just short of the big turbo and associated tuning). That is not to say improvements could not be made and the power band improved however. In its stage 1 form, peak number increases were limited but max gains were recorded as high as 31 HP and 31 lb-ft of torque in some cases. Gains average 12-15 HP/lb-ft increases across the power band however. While by the numbers it may not look like much, it feels more fluid and eager on the road. Power simply comes on more noticeably at 3500 RPM and the tuner continues to hold the increases all the way to red-line for a more enjoyable experience. Its a great foundation to build upon while we explore the big turbo possibilities and extract what we expect to be very solid gains out of that next step. |

The only new release in suspension was the coil over (HAS kit) which was posted in the suspension section (http://f87.bimmerpost.com/forums/sho....php?t=1296133). The rest of the stuff (sways, toe links, monoball) can be found on the Dinan website as they have been available for awhile.

The combination of the 3 doesn't yield any meaningful improved power... hence the lack of the stage 2 tune. Simply wasn't anything being gained. On a stock car the intake yields some performance improvement but when the car is tuned the tune basically cannibalizes any gains you get from the intake as the car is simply tuned from the factory pretty close to its limits. This may change when the intercooler and/or upgraded turbo is put on the car and the vehicle is allowed to breathe a bit better and the intake temps reduced but on a tuned car the intake is basically for improved throttle response, looks and a bit of sound.

Don't see the point of pushing much farther unless you have a bigger turbo on the thing. Just going to be producing heat at that point with no gains. Unless they are pushing up that large delta amount in the lower RPM's just to have the torque surge. Which I guess you can do but just give you a bit of whiplash. Dinan has always been more about a gradual steady power build up and smooth power band in general. Not slamming you back in your seat at 2500 RPM just for the feel of it. To each their own. Surprisingly very minimal. The M2 has a lot of sound proofing in it. Part of the reason why it doesn't weight much less then the M4 (with less sound proofing) even though its considerably smaller. I'm surprised the exhaust isnt getting more love in this release... its the crown jewel of the release and at a price point you cant go wrong with. |

Dinan, thank you for a well thought out package with a little more power, improved throttle response, better handling, and great sound. I for one appreciate your NO B.S. approach to performance. So many out there peddle #s that mean very little.
Does the exhaust shed any weight over OEM? |

In regards to the exhaust weight, while it's physically quite a bit smaller then the stock exhaust it unfortunately does not shed any meaningful weight. If I recall correctly it was lighter by 2 ounces or some trivial amount. |

BTW, though, you can make a sport cat downpipe that flows better than stock, throws no CEL, and sounds great through the stock exhaust (let alone Dinan's, I'm sure). |

Just to clarify, by "done with the M2 by years end" you mean the full panoply of kit options will be available for sale by that time? No additional wait for CARB approval, like with the big turbo on the M235i, for example? |
