DIY exhaust resonance cancellation

[b454rat]

All the exhausts I've had over the years, never had drone bad enough where I wanted to do something. Prolly the loudest truck was my old CCSB with a tired 5.7, headers, cats, H-pipe, dual Cherry Bomb extreme I think they where called, kinda like a Flowmaster type muffler, 2 1/2" up to the mufflers, then 3" out the back, then 5x24" tips going all the way straight out the back. It was LOUD, and super throaty. But even cruising at 70, you could have a conversation without yelling, and don't recall any drone. To me that is the sweet spot where the exhaust sounds the best lol....This was discussed on the Tundra forum too. I put duals on mine, and, no drone.

biggest think i find helps is get the exhaust all the way out from under the body . no turn downs or dead stops under the body .

my old plow truck i had it dump under the bed and it droaned so bad . all i did to fix it and make it 1,000x better was a tail pipe out to the bumper and wow was it better . that was a flowmaster 50 delta flow 3" in/out .

next is muffler past the rides seat or if truck past the cab .
