Subject: Re: Dynomax VT No Drone mufflers by jmartynuska on 2010/4/30 10:16:24 Not to hyjack the thread....... I think it could work. I've felt the source of the C4 drone is the Y intersection post main cat, where the single pipe out of the cat branches off into two pipes. No real hard data to back this up, but my theory is turbulence at that point causes the drone. I had a single 3" pipe off the cat through a resonator put on my car - primarily for weight savings - but also to test the theory. Plenty of power, mileage went up, and no drone at cruising speeds. Still a little noisy but it doesn't have that annoying drone and I can hear the radio and myself think; a muffler vs a resonator might help with the noise. Looks like this muffler works on the idea of cutting back on reversion - air running back down the pipe. Valve opens to let air out, closes to prevent air from entering. Thoughts? |
