Request: muffler sound hierarchy
« on: November 19, 2014, 01:46:10 AM »
I have a 2014 C5 and would like something very slightly louder than the stock muffler.
Any info I can get about relative sound levels between mufflers would be helpful.

How would you compare the EFI to a cocktail shaker? Louder than stock but quieter than a cocktail shaker?

NFG has sound files for the cocktail shakers. Check out their you tube video or the online catalog.

I put an emgo shaker on. Has minimal baffle that's removable. It's loud!  ;D

Nice comparison I can see/hear the reason for the EFI short muffler now, it does sound a lot better, do you still get the flutter on overrun (closed throttle)?

Here's what my twin sounds like with a pair of unbaffled cocktail shakers.

EFIs have a great sound that doesn't horrify the neighbors. Cops won't even notice you, but it's loud enough to be a joyful noise when you ride it. My favorite.

+1  I have the EFI silencer from our host and find it to have a nice balance between throaty thump and reasonable volume.

I've got the EFI. They (sometimes) have a little baffle installed in the end that makes the sound rather "brappy." Once you take that out, the thump shines through.

I've heard the NField Gear cocktail shakers as supposed to have a bit more bass than the EFI silencers, so I'm considering experimenting with one. My EFI silencer has battle scars, anyway.

My 2010 G5 Deluxe has worn an original British 1960's NOS cocktail shaker since I got it. I like it & would not change it. Although I left the shower drain plate baffle in mine, it does bark & snarl when caned, but is not unpleasant at lower RPM. LEGAL? I ask you, would any sane person knowingly get on the throttle in front of a policeman?  In fact a wide open megaphone becomes nearly silent when you close the throttle & pull in the clutch.

I had a dealer installed EFI muffler on my bike from time of delivery until a few months ago when it self destructed. The complete inner baffle assembly broke free and rattled like crazy. I loved the performance and sound of the EFI muffler, too bad it only lasted two years. I have a Harley muffler, off a softail I think, on it now with a 3/8" hole drilled through the internal baffle. Its OK but not as nice as the EFI was.

B5, like a Model T, comes in any color, as long as it's black.
