Performance mufflers which ones????? - 06/09/13 03:18 AM
My 68 GTX 440 with big Voodoo cam has Hemi style mufflers and stock manifolds. Had a wicked drown at 30 35 miles an hour. Put a set of magnaflow resonators drown gone but did get quite a bit quieter. My super bee 440 with 509 mopar cam X pipe and dynaflow mufflers sounded mean but same thing had a wicked drown at 30 35 miles an hour again went with magnaflow resonators drown gone but so is the mean sound. Any one with cammed up motor and stock manifolds found a good performance muffler that sounds good with no drown ?

I have the often bad-mouthed flowmasters, 2.5" pipes w/ H-pipe, mufflers just before the axle, no drone

I have the Dynomax Super Turbos (the ones with "flow directors") on my Hemi RR 2.5" system w/tips, and they have a nice crisp but not tinny sound, no drone, sound great. I'm putting a pair on my 3"-system BB wagon street strip car too.
Had a 406" Duster, 2.5" full exhaust & tips, that had Flowmasters or a knock-off of them on it, very similar sound quality to my Hemi car but no drone.
(To run 2.5" through factory tips, the tip inlets are too small, cut them off and weld to the bulged area.)

I would love to find performance mufflers that are as quiet as stock hemi or six pack mufflers for my 500" stroker with manifolds.

Anyone tried the Dynomax VT's?
Nice throaty sound until about 40MPH then no drone.
