In 2013 I had a 359W hydraulic cam making about 500HP I bought the 3" cobra packs 24" with No packing louvers facing forward, tips 90* My sound test with a iphone app was 93dB at 20". Thats all the information I can get from my notes.
After 7 years of Autocrossing my engine gave up. I built a 408 solid cam engine with some intake work. It dynos about 575HP. During autocrosing events last year I was told I was too loud and needed to quiet it down or not race. Honestly It's hard to tell with a helmet on but I don't think it's much louder than the other engine, I think they were concerned and trying to be good neighbors during the covid year, but OK I get it. I refused for a couple of reasons, 1) I liked the sound and 2).my vertigo came back and I just can't do it anymore. sucks getting old fellas.
A month ago my wife and I went for a ride. After the ride she asked me if the car sounded louder to me because we could hardly hear ourselves talk while driving. I also noticed this. Call it old age or something but I knew I had to do something different just to take the high tones out and still keep the horsepower. A little dance if you will.

I called Eric at Classic Chambered (great service and a quality operation) and I ordered the 26"X3" cobrapacks With packing. I installed the flow mod just like the the last project and again louvers facing forward. I turned the tips down 20*
When I test them this week I'll let you know what I think I'll use the same dB app as last time. It's not apples to apples comparison, I realize this but I'm hoping to take the high notes off and deepen the sound.
