One word... WOW!
I thought I was amazed by Flowmaster exhausts before (I have the American Thunder system on my truck). Installation of the Outlaw system on my Challenger was super easy, and when I started it for the first time? Yep, WOW! Throaty music! At idle it's a dull rumble, but when I open the throttle it sounds awesome! Five Stars all around... I love it!
Headers look great,good welds, smooth bends. Feels solid. Instillation was not easy,but with a lift and a fiend to help it wasn't terrible. Combined with CAI, cat back exhaust they really woke up my 2010 Challenger 5.7. The engine spins up much quicker than with stock manifolds. Sound is about the same. Not noticeable louder inside. No dyno numbers but seat of the pants feels like 25-35 more horsepower.
