Review on Flowmaster 8430152 Super Muffler 409S by Angelo Forrest

I was looking for a slightly more aggressive sound from my current exhaust and muffler. My 5.3 liter Silverado truck originally had a "turbine" muffler. The previous assembly and processing was poor, it started to rust and had a hole. Decided to stick with this Flowmaster muffler. Hardly any difference in sound. It sounds better, but with the restrictions that trucks currently have, it limits the overall sound. I considered removing the cat but changed my mind. Overall I'm happy with the finished sound it produces.
