Flowmaster 817563 Outlaw Cat-back Exhaust System

The media could not be loaded.  Whoever said this exhaust is too loud, has no business owning a muscle car! I have a 2012 SRT 392 Challenger, it took me and my buddy about 30 minutes to remove my old exhaust and install this baby. After staring up, I immediately knew something was different! When I mashed the gas pedal I woke up the neighbors! The real fun was when I got in it...the sound is indescribable at best! This is what it is supposed to sound like! Stop reading this and slap these joints on your Challenger; you’ll thank me later!

Awesome, sounds great. Louder than I thought, but good low sound at idle, very powerful full throttle. Highway speeds sound good, nice low rumble. You can really hear the engine throughout the RPM's. Gained some HP as well. Went from 4.56 to 4.39 (0-60) and gained 1-2 MPG (if i keep my foot off the pedal). I had to make slight mod to the clamps, they were too tight as is, but fit good once on (not a lot of back pressure to leak out though).

It was a perfect fit for my vehicle and the tone is a deep rumble that explodes into a roar when i hit the accelerator. Flow master is what you want if you have a hemi and you want it breathe.

Great exhaust. My 392 went from mild to loud in about two hours. I love it now. My wife, neighbors and all the animals in a one mile radius hate me, but I love it. There is a drone at certain RPMs, but usually only when accelerating at a moderate rate. At cruising speeds it's a pleasant growl.

Good, not great. I like the rumble, but as others have noted, it makes a backfiring noise frequently. Wish I had purchased something else. You will not like this product.

Mop faster for better. Me car now go faster. Mom shaky mr honey. Three foreign have loosed me nAbru. Thank you fast far maker

Awesome sound
