Hi Everyone,

I was looking around a few websites regarding rear exhaust pipes and i came across
this system design, i haven't seen anything like this before......

just wondering if anyone has installed one of these on a v8 of some sort??

Or knows any further information on them??

Apparently there is no drone at all....i found it on the following site if anyone's interested.

Capped Helmholtz chamber (Drone Eliminator)

Thanks

Jesus! You got ear plugs?

hahaha... the bottom one just ignores the rear muffler altogether!
hope whoever installs it has a fred flintstone flap on the driver floor so they can use their legs instead of the engine when driving past a cop!

"No drone at all" , only because your ears just exploded and you've been pulled over by cops and slapped with an EPA notice.

Wouldn't be THAT loud. There's still mufflers under the car. Can't really see it sounding good though.

Remember seeing something like this on here or another forum a while ago about it. From what i remember reading they are big in the states and drone like crazy.

They're all over youtube if you want to check them out - they're big in the states.

I'd take a punt though and say they might just be a tad over the dB limit... just a tad though.

Not that loud??? There's FA difference to driving around with no rears!
