Product Details

The Flowmaster 817477 American Thunder Cat-Back Exhaust System delivers a moderately aggressive exhaust note with performance-oriented engineering designed specifically for RAM trucks equipped with factory rear bumper exhaust cutouts. This complete cat-back system features mandrel-bent 16-gauge stainless steel tubing for maximum exhaust flow and durability.

Key Features:

  • Dual outlet 50 Series HD performance muffler for enhanced sound and flow
  • Mandrel-bent 16-gauge stainless steel construction throughout
  • Polished 4-inch stainless steel tips for premium appearance
  • Moderately aggressive exterior exhaust tone
  • Designed to clear factory spare tire location
  • Utilizes factory hanger locations for straightforward installation
  • Engineered specifically for RAM trucks with exhaust cutouts in rear bumper

This American Thunder system installs easily using factory mounting points and comes backed by Flowmaster's lifetime limited warranty. The precision mandrel-bent tubing maintains consistent pipe diameter throughout each bend, reducing backpressure and maximizing exhaust flow for improved performance and sound.

First off, I LOVE my new shipments! These guys had everything at super low prices, and the shipping was phenomenally fast. It's all working great, and imm definitely buying from these guys again.

Ordered a sling to store my roof rack. There was an issue with the supplier which was quickly resolved by the Autoplicity staff. Great customer service -- most responsive I've ever seen.<br><br>Best prices around.

I ordered the Dee Zee truck box rails and the price was the best on the net after searching. Also, fast shipping. I would recomend this site.

Super easy + best price on the web. Very pleased am I.

Great service. Shipped out the day after I ordered it...plus it was the cheapest of the competition.

I bought a Motive pressure brake bleeder from Autoplicity. I have been looking around for different prices for quite a while, and their price, even with shipping cost, was the lowest. After ordering, I received a notification of shipment and tracking number. The item arrived well packaged, complete, and intact within a few days. I am looking forward to using it.

Cheap prices, great quality, and fast delivery. Autoplicity will continue to receive my patronage.

Easy and fast. Order arrived very fast. Thanks.
