To the other two who recommended adding a cherry bomb (essentially a resonator) how will this prevent drone in the existing muffler?
The exhaust pulses going through the pipes create an unpleasant resonance. That resonance is the drone you hear.
Adding resonators modifies the resonation and reduces the effect.
Is this achieved by increasing back pressure? I never knew that it was the resonance in the pipe that caused the drone, always thought it was the muffler?. I'm just the kind of guy who really likes to know what's going on before I spend cash.. (Read cheap! Lol)
As and UPDATE TO ALL: they are currently a Dynomax muffler 20" long body and about 24 1/2 to 25" long from tip to tip of the inlet & outlet. The inlet and outlet size mic'd to be close to 2.5". Do they use ID or OD for determining what size inlet and outlet are? From their web the best i can say is they are the 17513 model.
It is also a welded muffler. Does mean it's stainless?
I'm not adverse to adding a resonator, but I really don't want to butcher the exhaust further if this does not cure it..
All this input is great! Please continue!
