Has anyone installed a Moroso spiral resonator? I need about a 7db reduction but I don't want to add too much back pressure.

The dynomax bullet mufflers only give 2-4db reduction and other companies bullets are too big in diameter.

Opinions?

I'm running them on my true duals, and with my x-pipe bolted up its ALOT quieter than open headers. It's no quiet by any means, but compared to open headers it is.

Ok, thanks for the info! I'll be running a single resonator along with my Hooker aerochamber, I have to pass a noise inspection in Germany
