D&D Exhaust ?

[fouramdesigns]

Anyone familiar with them or have tried them on their Duc? I have Termi's with ECU and BMC chopped box at the moment.

They'd be plenty loud and fairly brash with little tuning/tone.  They're also commonly associated with squids on I-4 bikes too for some reason.

A nickname I've heard for them is Deaf and Dumb.... They are loud so they'll make you deaf, and they sound dumb in the process.

Some one here picked up an s4 with some and they were quickly swapped out.

I had one on my Kawi ZX9R and the tone was deep, loud and mellow. very pleasant and powerful for that bike, but not annoyingly loud and obnoxious.

However, I'm not so sure those pipes would translate well for a Duc. Try doing a search on youtube to see if anyone posted their bike with that exhaust (that's what sold me on the termi's).
