Need to start looking for a muffler for my 2.7 conv. Whats being used? I have no problem with fabing the valence for dual exhaust. Thoughts on performance, noise, ect.

“Single out regardless of brand you will get almost zero drone.”
I think what I am hearing is the converse is also true - “every two out has drone”. That has been my experience in playing around (amateurishly) trying to build a drone free two out. I have tried what I thought were some clever internal baffling schemes to no avail. The water cooled sixes seem to use a lot of two outs without drone. One would think that the acoustic harmonics are similar. But if Ben says that it can’t be done that would be enough to convince me. I have been thinking a removable plug in one of the outlets is the way to go - out for a social drive and want relative quiet, - insert the plug. Out to a car cruise and want unfettered wail - pull the plug and tolerate the drone. Care to confirm or deny Ben so that I can give up on the quest for a drone free two out ? |
