Manifold Back Dual Exhaust

[1984 K20]

I was wondering if anyone knows how loud or how many chambers the turbo mufflers have that are on the manifold back dual exhaust that   sells. I think it is made by Heartthrob and is sold by JCWhitney too. I was also wondering if anyone has that system or knows of any websites that might have a sound clip of it. Thanks

I put that system on my 86 silverado with a 305 for me the sound is perfect , it 's not to loud, when you get on it it makes a nice roar
