Awesome exhaust couldn't be happier
I bought this exhaust about a month ago and I'll tell you I couldn't be happier ...I have a stock 2015 challenger RT and the outlaw exhaust is the way to go ..originally I was going to get the American thunder but I read reviews people said it wasn't loud enough and it almost sounded stock ...the outlaw has minimal drone with loud output ...trust me it's a head turner and people will give you thumbs up ! And your neighbors might hate you on a cold start ...plus big thanks to Jegs for the fast shipping with no cost ...
Best sound for your challenger
I bought this exhaust about a month ago and everythime I get in her and start her up it still puts the biggest smile on my face. If you want a throaty screaming monster then this is the exhaust for you. At every rpm range you can never be upset with the sound. It is a very loud exhaust, so I hope you hate your neighbors :)
Great sound fit good
After studying this for 6 months I got the flow master outlaw system for my 2015 challenger although not for the faint of heart it sounds great at startup it wakes you up actually can scare someone standing close awesome rumble at idle and very aggressive under excelaration.. nice sound at cruising speed 70 mph. Sounds the best in the sport mode.
