Why yes, Rob, I do. I can honestly say if you don't want the Flowmaster drone, don't buy a POS Flowmaster. Get a A Dynomax Ultra Flow. Mine sounds great with zero drone, even on a raspy slant 6.

Not anymore, Tom. Thanks. I used the Ultra Flow on Vixen with the TTI 2.5" full exhaust from the manifold opened up to 2.5" and there's no drone at all. Just cool exhaust note.

Thanks, I fully believe with longtubes and an H-Pipe rather than my X-Pipe it will sound better. I’ll be doing both over the Winter.

JohnK, just saw this buried in the string; sorry for being so late offering an answer. The X will help but it will not get rid of the flowmaster drone. if it were me, I'd adapt Dynomax 17748 muffler son and be done with most, if not all, drone and you will also enjoy enough exhaust flow to handle your power PLUS it still sounds like a 340 should. I ran mine for years but just put them on an LS3 powered 1957 Chevy Truck to get rid of noise from magna flow short bodied straight through mufflers. Hope this offers an alternative that helps you.

Voetom, I'd like your opinion. I have a 1970 Duster 340 with 833 trans. It currently has OEM manifold,
2 1/2" H-pipe exhaust with FlowMaster 40's and piped to the tips. I like the sound but do have drone at cruising speed. I am redoing exhaust using TTI long pipe headers, 2 1/2" X-pipe exhaust to the tips. Would like your opinion on mufflers. Engine Masters showed that X-pipe exhaust quiets the sound so still looking for that muscle car sound out of my system. Street car use mainly. Your thoughts? Thanks.

I'm still trying to fix the "drone" in my car. I have 2.5" Hooker long tube Headers with an X pipe and Magnaflow exhaust. I just added Vibrant 1142 3" "ultra quiet" resonators and while it did tone down the drone a bit....it didn't eliminate it. My next step is adding sound deading to the interior of the car to see how that helps.

Moral of the story is flowmasters still suck... but spending more $$ and doing more work can make them less annoying while driving.
They don't flow for **** and they're obnoxious sounding.
H pipes quite everything, just imagine how much quieter and better flowing a quality muffler like dynomax would perform in that setup.
Fwiw too many hanging points will transfer the noise to the car body.
I only strap at the muffler before the axle like factory and the tail pipes.
No drone.
Dynomax's aren't the answer either. My Walker's are quiet, #21856. Throwing away the new Dynomax's on the '72 318. Already have the Walkers on my '69 418. Lets hear the engine, not noise.
These Flowmaster resonators solved all the drone on my TTI 2.5” exhaust behind my 6.1 Hemi Cuda.
