Customer Reviews

American Thunder Series Cat-Back Exhaust System, Made Of Stainless Steel 8, 5.6
The parts install itself was very smooth. What needed to be done to get rid of all the corroded and seized bolts was another story. All in all, very happy with the sound it produces. Not too loud at idle and doesn't drone you out going down the highway. Feels like the truck runs smooth again!

American Thunder Series Cat-Back Exhaust System, Made Of Stainless Steel 8, 5.6
Great exhaust with stock sound.
Great exhaust if you are looking for a replacement for the overpriced ($1K from the dealer) stock OEM unit. I didn't want some crazy loud aftermarket exhaust and this was perfect. It also has a nice tone with minimal droning in the cabin. This was installed on a 2004 Nissan Titan in less than 45 minutes. Some have said there are noticeable gains in power but I can't tell. It feels just like it did with the stock unit. Overall this is a great product.
