NEW RELEASE: Free Flow Exhaust / Mid-Pipe (F22 M240i)

Name:  F22_M240i_Exhaust_Banner.jpg
Views: 5967
Size:  130.2 KB

Based on the wildly successful F30 340i exhaust, the M240i exhaust exhibits the same aggressive burbles and intoxicating sounds as its predecessor... perhaps even with a little more attitude.

Dinan engineers designed the F22 M240i exhaust to improve exhaust flow by reducing back pressure, resulting in increased power output and a great sporty sound that is civilized when you want it to be, and pleasantly aggressive under hard acceleration. Not only is the tone improved but the additional burbles and pops that come with it are simply intoxicating. Dinan also incorporates a Helmholtz chamber design that reduces resonance or "drone" at low RPM.

The system is built to exacting specifications to ensure perfect fit using the factory hangers. It is made from 100% 16 gauge 304 stainless steel and will resist corrosion for years to come. The design features twin 89mm (3.5") ceramic black or polished stainless exhaust tips for a tasteful, high-performance look.

For those that simply want a bit more volume the optional Dinan High Flow Mid-pipe for the F22 M240i allows for an aggressive tone to be achieved out of the stock system. Coupled with the associated Dinan exhaust the sound is further perfected into an aggressive growl that is hard to ignore. This full mid-section removes the factory center section, including both resonators, and replaces it with straight through 3.25" T304 stainless steel tubing for better flow, and sound while also reducing the weight by 3 pounds.

Benefits of the Dinan Stainless Free Flow Exhaust for the F22 M240i:
  • Uses the factory brackets and hangers for a factory-like fitment.
  • Helmholtz chamber to reduce drone.
  • Enjoyably louder, sportier Sound
  • 100% 304 stainless steel construction
  • Twin 89mm (3.5") laser engraved ceramic black or polished stainless exhaust tips
  • 6 HP @ 6600 RPM, 5 FT-LB
  • Factory computer controlled exhaust valve is eliminated.

Mid-pipe diameter is 3.25" (82.5mm) and will work with the stock muffler and Dinan muffler alike. Stock diameter of the midpipe is 80mm in the very few round sections of the pipe.

So the stock muffler will slip into the Dinan midpipe ?

Does the midpipe come with the hangers to the car ??

I just entered the Dinan page to place my order but i found out the midpipe alone have a ground shipping cost of 55USD to FL. I thought the shipping was free.

Any coupon or discount for forum members ??? Dinan_Engineering

Thanks.

Yes they stock exhaust will slip into the midpipe. There is one hangar location on the midpipe--- same as stock.

Shipping is free if the total for the order is over $500 (before tax). Feel free to contact your area sales guy at 1-800-341-5480 x2105 and see if he can waive on his end. You can also purchase directly through a dealer and wouldn't get charged shipping as an alternative.

We do not offer coupon codes. Keep telling the web guys to remove the option from the shopping cart but alas... Goes against our MAP policy and new distribution philosophy ultimately.

Never been tested hence its non-inclusion. Historically the verts have an additional brace or some other element that doesn't make the midpipe fit without some form of modification though.

Stage 1 And Muffler

thinking about having my dealer do the install of your stage 1 ELITE and just the new muffler,what would the install time be for the two of them and what would the added horse power and torque be , I have 3200 miles on my M240i coupe also can the stock rear defuser be used

2.3 hours between the 2. Power gains would be the gains from the tuner. For all intents and purposes the exhaust is a sound mod. There is some small gains at the ultra top end but its nothing you are going to feel.

Is the midpipe then not just a sound mod but a power mod if I coupled it with my elite tune? I have a MPE and am thinking of coupling the midpipe with that. Thoughts?

No power is being made by the inclusion of the mid-pipe. Purely a sound modification. I would shy away from the mid-pipe personally if you have the MPE. On other models, can't say for sure with the M240i but have to assume it would be the same, the mid-pipe doesn't mate cleanly with the MPE and would require some modification.

Would the midpipe accomplish the same thing that a dual resonator delete would?

What's the correct torque for the clamps ? I don't see that number on the installation instructions...

Nether of the guys I would ask are here today. Tight so the pipe doesn't move would be my answer. Super scientific, I know. Contact tech support and they may know off hand. Even if they don't they could get you the information much more readily then I.

Thanks. I asked because BMW does recommend a torque for their MPE.

This concerns me as the cut is made at the factory dimple location and the MPE slips over the stock pipe. It should not matter if the cut is a bit uneven.

Is the mid pipe the same diameter as the stock mid pipe? The M235 MPE does not have a slip fit connection (relies on clamp) the M240 MPE slips over the midpipe.

Mid-pipe is larger than OE as indicated in an earlier post and slips over the stock muffler inlet being tightened with an 80mm clamp. We base muffler design by set stock points--- one of them being the stock inlet pipe location for guaranteed fitment. If the MPE uses an 80mm clamp as part of its kit then that would indicate that they do the same thing as us --- just in reverse--- assuming you are correct in that the M240i MPE slips over the midpipe. If that is the case it would technically work but would require a coupler and not a clamp to tie the 2 pieces together.

This is all just guesswork though based on loose information since we haven't seen a MPE equipped M240i in the shop however.

Ugh ... I see fitment problems if this will not slide into the MPE. Damn
picture on the right is the stock exhaust cut at dimple (top) MPE with included clamp (bottom)
picture on the left is MPE installed to the stock midpipe cut at dimple

this may work IF the Dinan mid pipe is the same size as the MPE (as it is made for the stock tube to slip in) BUT the MPE has a clamp welded on / relief cuts in the tube. you will also have to cut the Dinan part down as it is made to fit the stock exhaust cut at the dimple.
