or is still trying to figure out which one to by. I am still looking.

Philip,

Does the Dinan exhaust eliminate the drone while keeping the stock mid pipe?

How will the OEM warranty be affected?

Read your warranty for starters. It's foolish to have someone else tell you what is or isn't covered unless that person is your lawyer. I believe each state has its own laws for auto warranties which can complicate matters. Personally, I don't see how an axle-back exhaust can compromise anything on your car?

Yes it eliminates drone while keeping your stock mid pipe.

Dinan matches the BMW warranty on any product that is not marked "Race Purposes Only." So with this exhaust you would have the exact same BMW warranty and no BMW dealer would question it either because this is a Dinan product.

You shouldn't have a warranty issue with any axle back exhaust either but that all depends on each dealer since some are more forgiving than others but they all know that Dinan matches the BMW warranty so there would be no problems going with Dinan.

Am I missing something. My understanding is that the DINAN exhaust is shorter than stock not longer. This should allow one to remove the OEM unit,keep their stock exhaust in tack and use a flanged extension to make the connection without cutting.. That being said, I agree that it's pretty lame not to make it a true bolt on install.

You're incorrect. The stock exhaust is a single piece beginning from the flanged connection at the rear of the mid pipe. The Dinan exhaust requires you to cut off the muffler because it does not come with a connecting pipe that is included with most aftermarket 1M exhausts.

Why dinan does a cut and clamp we never know and i agree i dont like the cut and clamps either. FAIL DINAN

[Mrated]

That was a big deal breaker for me, I was ready to jump on that 15% off deal and go for the black tip one, but I wont now, I would like a real bolt on

[4thM3]

Agree that the DINAN is not a real bolt on. I also understand that the factory exhaust is one piece all the way to the flange. What I am suggesting is that any properly sized segment of exhaust piping with a flange welded to it (available inexpensively from a quality muffler shop) can eliminate the need to hack up the factory system.

That being said.....I can't figure out why DINAN chose the clamp approach. Makes no sense to me.. Tips are gorgeous though

I posted this in the original thread for modification lists but since folks are over in this thread discussing I will provide it again. Hope you don't mind.

Thanks for posting. It seems to be a nice, deeper tone compared to stock without being too loud. Since the Maddads should be contributing a lot, I assume Dinan exhaust alone is really not a very loud one which is not a bad thing imo. My set up has a similar tone as well (Evolve Race and N55).

On another note, from this picture I can say that the muffler sits quite low and visible!

In terms of the exhaust note. I had the maddad mid pipe first and once I added the Dinan the sound became much deeper than the maddad alone. I don't think the video does the lower octaves justice. When I blip revs when the car is totally warm, there is a very serious exhaust note and people come up to me all the time an comment on how that has to be a serious exhaust system. Second, the stock exhaust muffler has an internal valve that from what I understand from Dinan is actuated by exhaust pressure. Higher revs would open the valve. There is no valve inside the Dinan muffler. The pipes were installed as high up as possible. The perception from me and the distributor for Dinan that installed it is that they want you to see the muffler to some degree for a sportier look.

really? I have to cut on my baby... and they offer this as an explanation as to why the can looks like one of those civics driven by some teenager from the back?... and If so why not laser etch their name/ logo on the exposed region?..it looks like they had enough space to do it...
i call BS... sounds good though!

Never heard of this internal valve and none of the pics I've seen of the internals show such a thing. I have to call BS on this one. Most exhaust valves operate on vacuum and not pressure.

When I stated as high as they would go, I am speaking in terms of the tail pipes being pretty close to the carbon. I get the civic comment and that was my feeling at first however, as we know, Not a Civic.

I was told this information from Dinan's internal reps. It was either Scott or Chris which are the two reps for West Coast and East Coast.
