I have had the American Thunder catback exhaust on my 2014 Dodge Charger RT for a few weeks now. Initial torque is better and overall performance has increased. No better mileage as of yet, but I am having alot of fun driving my car now!!!!!!!!

This exhaust is perfect for my 14 tundra! If I had to do it all over again I would do it just the same. Awesome quality product with an aggressive sound that really hits the spot!

I didn't want something too loud because I'm a good neighbor. I settled on this 50 series as it seemed to be very balanced. Unfortunately, after install, I realized it was much tamer than I was hoping for. It's got a decent idle rumble but the exhaust note really fades after 2,000 RPM. I'd sum it up as a stock 60's F100 sound. It's whisper quiet at cruising speeds. No joy in stabbing the throttle. Also, the clamps for this kit are junk. Now I have to get it welded! Stick w/ a 40 or 44 series.

Although they say this is an aggressive exhaust system, I had concerns if it was going to be TOO aggressive. After a local shop installed it on for me, I thought it sounded nice, not too aggressive. The shop told me they had zero issues installing it. I definitely noticed a difference in performance after the install...a nice added bonus.
