Here is the 1st 914 2.0 muffler for @superhawk996 .. It turned out really nice .. I hope this product will be well received as we took along time to develop this based off of the 914-6 muffler factory design and implemented allot of those principles to the 2.0 muffler. Rumor has it may do a group buy or special pricing for okteenerfestAttached Image Attached Image

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.

Sorry for the newbie questions.

Do the factory mufflers use packing material, or just baffles?

What about yours?

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.

Yes to what superhawk said. We use a high end fiberglass packing.

Thank you both. I expect that a stainless muffler will outlive me. But, what is the life expectancy of the packing?

I have pulled apart mufflers that are 30 years old still having all the packing.
