Re: Ideas how to quiet my cabin drone noise please

Have same sound but only in OD. 36" real (1969) cherry bombs that point down before rear axle. No problem in other gears. Not real bad but can really tell when the 700r4 goes into od at 45. No need for a tach. Heard this is a very common issue but wondering if i added short angled extensions to direct exhaust back if it would affect performance. Have lots of room underneath and about 10" to rear axle. Would go out under original boards but the power boards are in the way.
