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!
The exhaust is nice and has a good note to it. It's not as aggressive as I expected, but my options for a system for my truck were limited due to having the v10. Bolted up easily, and only had to make one cut to the last pipe to add the stainless tip. Overall, I'd recommend this product.
