Contacted billy boat exhaust about their helmholtz mufflers

[Clint Beastwood]

Was looking at this https://www.bbexhaust.com/shop/universal-muffler-timbre-cylinder-wmuf-0705/#

I messaged them asking if they make anything that specifically attenuates the range that plagues us with drone, hopefully they reply back.

I’m really surprised there aren’t more mufflers with specific frequency targets - nobody discloses what range they target. Corsa has some quarter wave mufflers but they never replied when I asked about tuning.

I used a billy boat catback on my old audi S5 v8 and it was actually quieter than stock at various rpm (I did select the "stealth" resonated version). It was impressive that they managed to design a straight through system that could do at!

Like many people, I had never even heard of them before. Apparently they are popular with corvette guys.

I'd heard of them, I just had never needed a muffler half the weight of the car

Their stuff is BEEFY, like, you could move a muffler from one car to the next for 20-30 years and it'd still be fine.
BUT if the timbre tube thingy works then it's a great option.

I just emailed Bill at Billy Boat directly with my personal engineering data asking him what products he has that'll specifically actively cancel those frequencies.
