I am good with someone testing it but am not down for tweaking each unit for sound levels.. One thing I have learned is that when you sell a la carte you open your self up to a huge confusing mess.. Rewind 3 years ago when I offered the 914-6 heat exchangers up for the 1st time I offered with or without o2 bungs.. People were sending o2 bungs with all different location requests and trust me nothing was standard.. It really gets balled up fast. Fair enough and totally understandable. I was more thinking along the lines of offering a couple version for sound rather than custom tweaks. Even with that, I have no idea what it would entail in additional R&D and production costs, so you can just ignore my ignorance or give me one of these (IMG:style_emoticons/default/slap.gif) . In reality, I'm probably the only person on the forum who wants a muffler as quiet as I'd like so will settle for as quiet as I can get. (IMG:style_emoticons/default/smile.gif) @bbrock the only thing I might be willing to leave out is the packing material other then that the internals would stay as is which is a mirror of the factory 911 914-6 muffler just in stainless with slightly larger tubing and perfs. That would make it louder. Personally I like quieter now as I have gotten older. |

Looks awesome. I am guessing this is the same internals of your six quiet muffler? I love the sound and power of your quiet muffler on my 3.2 six. I can actually talk to people inside my car with no noticeable drone. |

(IMG:style_emoticons/default/thumb3d.gif) Where I live, loud motors are a lot harder on wildlife than people realize and I've seen real changes in wildlife in our valley as the number of loud boy toys has increased. It's pretty important to me. It seems most people want their 914s to growl, but I'd prefer mine to whisper. (IMG:style_emoticons/default/biggrin.gif) I'm very interested in your mufflers. I have a NOS Bursch that I want to experiment with different muffs, but don't see it as a long term solution. I know the quality of yours will be second to none and a lifetime investment. |

I do intend to build an engine test stand once I have an assembled motor. Would be glad to sound clip at that point but given I have a skin graft scheduled for Monday I fear that engine assembly may be a few months off.
I guess I’m only one in Detroit with a 914?? I assumed we had one or two more around here ??? |

700 SIMOLIANS FOR THIS BAD BOY?
Can you post photos from different angles of it mounted on a 2.0L car? |

I have enough flanges laser cut for 9 of these. Who is in?? It does not look like it would fit a stock 1976 2.0L that currently has a Bursch. Is that correct? Does yours have stock 76 heat exchangers? Yes. |

Right now running 2.0 exchangers. I should be done by the end of the week. Michigan Build |

Right now running 2.0 exchangers. I should be done by the end of the week. Michigan Build 1st phase of skin graft surgery this morning. Under doctor orders to not sweat for at least a week while I have some crazy vacuum dressing on the wound to help suck out fluids. Can you believe that crap? Anyway if you get to the point of being able to bolt on and run I’d be more than happy to meet a local teener and see if we can get a sound clip for Ben. Just PM me if you get close and have interest in trying it out. Nice engine ! |

@bbrock the only thing I might be willing to leave out is the packing material other then that the internals would stay as is which is a mirror of the factory 911 914-6 muffler just in stainless with slightly larger tubing and perfs. That would make it louder. Personally I like quieter now as I have gotten older. Sorry for the newbie questions. Do the factory mufflers use packing material, or just baffles? What about yours? Thanks. |

Thanks. I'll let Ben speak to his muffler. However OEM mufflers that I'm aware of all use packing material in one form or another. Adds a mellowness. No packing gets a tinny, high frequency reverberation (sometimes called shell ring) that isn't overly nice. Packing helps reduce sound to manageable levels by acting as acoustic damping. |

(IMG:style_emoticons/default/agree.gif) Yes to what superhawk said. We use a high end fiberglass packing. |
