I bought the American Thunder system it sounded great outside but the drone at 1600-1700 rpm in the cab was to bad for me,I swapped out the original 40 series muffler that came with the kit with a super 40 delta flow series and it sounds 100 times better just as loud outside the cab with a much deeper tone and no interior drone what so ever, I got such a good deal on the kit I didn't mind buying the super 40. Would buy again.

I received this as a Christmas gift and was thrilled. The packaging was a big box and was flawless. Even the fasteners came in individual heavy ziploc bags. Installation was a breeze. (I have a 6" lift and did it in my driveway.) Everything fit and lined up perfectly - with just a few minor adjustments before tightening everything in place. Sounds and looks great.

It's OK but not as Racy as I wished. Should have gone with the Outlaw system with the black tips. I was worried trepid about committing to the loudness of the Outlaw, but after getting the American Thunder system , and watching YouTube videos with my truck having the Outlaw I wished U had chosen otherwise. Having said that, I would rate the quality of service from Auto Anthingvthrough the roof. In most cases my orders come the very next day having been shipped from San Diego. With free shipping!

Great exhaust. Sounds AWESOME. Pros: Growls when started, Quiet at idle, rumbles when you get on it. Cons: low tone DRONE at 1800 rpm which puts mph at 60mph. cruising speed.

I have had flowmaster for years on all my sports car and now my truck. The American Thunder series is awesome. Just the right amount of rumble and a few extra horse power. And it's not to loud in the cab which I was worried about in the beginning but it's perfect. If your just cruising you hear just a small amount of the nice rumble but when you get on it it's fantastic the deep and aggressive rumble you hear coming out of the truck. Now my truck sounds like a truck should. Recommended it !!!

This exhaust souns and looks great. My one issue is the nuts and bolts to hold the chrome tips on were way to small. I hope this was a slip up in packing the parts. I installed this in about an hour in the parking lot were my Wife works. It was her 60th birthday gift. She came home from work smiling from ear to ear. Great system, I highly recommend it!

Overall the quality, price, and easy of installation is far superior then any other exhaust system. Highly recommended over any other system esp when you can get them on sale.
