Holy crap did I make a good decision...Roush exhaust and intake are amazing. Swapped out my Stainless Works catback for the Roush and couldn't be happier. Don't get me wrong, the SW catback was great with a nice deep tone, but this Roush combo just takes it to the next level with absolutely no drone (the SW was pretty much drone-free as well)...it's loud in the back seat, but it is NOT drone. Drone is annoying and gives you a headache. This Roush is loud and puts a huge smile on your face!
