has anyone installed anyone of these on the hemi trucks?
i have the 14'' magnaflow and i want more sound. The muffler shop said no on the 50 and get the 40. Flowmaster said to get the 50 HD because it was made for the hemi. muffler shop said it will be like what i have now, but they only sale the 50SUV and not the 50HD. Flowmaster said the 50HD is louder then the 50SUV. plan on dumping before axle. I took off the magnaflow and put two Borla XR1 mufflers and i didnt like the sound. So those will be for sale locally only lol, SO now i need to decide on the flowmaster. Anyone has the super 40 or the 50 HD installed???

Flowmaster HD 50

I was at a car show in O.C. Maryland and the Flomaster Reps were there. We discussed the best system for the Hemi with MDS and they said the HD 50 was it because they have built in resonators which help with the 4 cylinder noise. Also since the 50 is a moderate sound and not aggressive, the difference between the 8 and 4 cyl mode is not as noticeable. I have the American Thunder single to dual exhaust system with the HD 50 on order.
