Flowmaster Super 40 vs. Original 40

I have flowmasters on my 1974 Satellite Sebring Plus 340 and I love them! I run Hooker Headers, 2 1/2 inch exhaust, Headman Hedders X-pipe, flowmaster 40 series. I don't believe that any muffler can sound any better!! I will admit they are a little loud in the car when driving but then again, it is a performance vehicle. I am using the same mufflers on my 1966 Valiant 340 project too! What can I say, the sound they produce kicks ***!! :thumbup:
