Review on 🚗 Enhance Your Ride's Performance with the Roush 421145 Exhaust System by Chris Estes

This system looks great! And it's loud! I like that. It has a great rumble at idle and at higher revs it sounds like an exotic car. At freeway speeds I noticed a slight hum, but not too bad. After a few days I got used to the sound and love it even more! Tunnel, oh my gosh, drive through the tunnel, roll down the window, put in some gears and enjoy the great sound! It has such a cool popping sound when braking. One cool thing I noticed is I get 4 mpg more! Even with hard driving and hitting, the mileage still gets better than before. Mixed driving: I used to have 22-24, now 26-28.
