Dansk orig muffler to B&B Headers?
Has anyone succesfully fit an original style Dansk 2 in 1 out muffler to 3.2 B&B Headers? Do the Header pipe outlets match up to the muffler inlet? What does it take?

I think that you would have a tough time mating those parts.
the horizontal spacing is different, the vertical height is diffferent, and the angle of the flanges is different

I wonder if a short adapter pipe(s) with appropriate flanges could be fabbed? Some Pelican has likely sorted this out... right?

I thought you had a turbo?
It could be done but it would be quite a job. Would start by removing the factory entry pipes. To the outside of the stock entrys are bulkheads that seperate the two end chambers. It is trully a one out sport muffler you could make new entryes in to the end chambers. Howerver, the side that has the tail pipe you would have to cut a hole through the bulk head. If it is not a sport muffler you will also have to cut a hole through the other bulk head to gasses can get into the mufferl where intended. When done, the muffler may be a some what louder than designed as one section of the muffler will be bypassed. A better way would be to cut the bottom sections off from the outside tips of the muffler up to the second bulk head. Cut off the bottom half of the outside bulk heads. Then make a new partition that runs from the second bulk head to the end of the muffler along the seam of the muffler. This will get the gasses into the muffler as orignally intended. Then you can add you can mount the can into the car and add your new entry pipes into the bottom ends as needed. It is much easyer to adapt over to the 993HE's. As you see, a lot of effort and may not be worth it. |

[QUOTE=911st;4681299]I thought you had a turbo?
I do... have a couple actually and a few other fun cars also. ST Thanks the thorough explanation.. agreed its probably not woth it. I may have to abandon the B&B headers...go to SSI's and the Dansk. I think they should bolt up together without too much issue...Right? I understand I may sacrifice a few ponies with the SSI/Dansk but a worthy trade toward sound sanity.

The B&B's make more power than SSI's. If you do not need heat the Euro Headers by George with a factory style muffler should be a bolt on that works well.
If you do not mind some noise on WOT how about a MagnaFlow or Flowmaster? They make the most HP. The MagnaFlow mightt be a little more civil but not much. This is pretty much a racing set up. If you own a muffler and every thing is paid for already it might not be that bad to mod it to fit. Dose not have to by to much more work than mounting a MagnaFlow or Flowmaster. Enjoy. |

The power loss of the SSI's vs B & B is not much concern... I would imagine we are talking about not more than 7 to 10 peak hp... and it's not a race car. Rarely do you realize the effect of peak hp in a street car, but you always hear the harmonic drone of the B&B muffler. Is there potentially a lower rpm torque gain w/ SSI's ? I am interested to check out the OEM 993 HE's w/ Dansk as an option.

I do not believe there is a low rpm gain w the SSI over the B&B. The B&B looks to make 3 more hp at 3500 and 10 more up top.
With a open exaust or the righ race muffler there is up to another 10hp available on top of that. SSI have a small low midrange advantage over stock HE w a cat bypass. It is tough to make much improvement of the original set up w a cat bypass and sport muffler. B&B and maybe the 993he's but not one has proven that yet. |

Another solution, and one that gets you away from the known fact of the BB mufflers being junk is to put a Flowmaster or Magnaflow on.

I tried three or four different mufflers on the B & B headers I had and could nt get rid of the buzz/drone no matter what

The Flowmaster just works so well at achiving the full HP on a 911 motor.
I do prefer the look of a bananna muffler w sport pipes out of the ends. |

Turbo3six,
I have B&B heat exchangers and the B&B 2 in 2 out and the same maddening drone at mid range rpm. Went to local performance oriented muffler shop and they took off the tips of the B&B muffler and welded in a reducing swage, I think 3-1/2 TO 2" on each side. Noticeble improvement in sound quality and no noticible power loss. Worth a try and doesn't cost much.

Maybe Ben (M&K) could make you one with the appropriate inlets.
