Fit was perfect. Easy to install. Not much louder at idle than the stock system but sounds great when you "get after it". Highly recommend this system.

Installed the exhaust by myself and with no lift. The sound is amazing and I absolutely love it! Can't beat the price on this aftermarket exhaust.

Amazing!

The sound is amazing but the install wasn't so great. Had to take my car back to the installer 2 times after initial install due to one of the mufflers hitting the universal joint, After hearing a lot banging from the installer they said "I shouldn't have a any more problems" I understand having to tweak things sometimes to make it fit, but that was my experience and so far I haven't had anymore problems.

I purchased this cat back system for a 2013 Dodge Challenger RT. The mechanic had no issues installing this system and everything went smoothly. The system reuses the OEM exhaust tips and keeps a nice stock appearance. I haven't driven the car enough yet but can say that there is definetly noticeable interior resonance right around 2000 rpm just like Flowmaster states. At other rpms the system has a nice deep rumble and cruising in overdrive at steady speed it's almost as quiet as stock.

The shipping was very fast,the system was very easy to install,it appears to be of very high quality. The clamps that are supplied are stainless steel and are very strong. The car has a nice rumble to it now,you can tell its a Hemi under the hood.The new exhaust is a bit more noisy inside the car, but i removed the resonater's also, and i only drive the car on week ends,so i don't mind, its not that bad.It only took 2 hours to remove the old and install the new system.

loud!

Great sound, really makes that V8 come to life. Need about 100 miles for it to really break in and give you that perfect sound. Really nice sound, definitely tuns heads, not overly excessive but quite perfect for a V8 muscle.
