Product Details

The Flowmaster 17104 American Thunder Crossmember-Back Exhaust System delivers enhanced performance and an aggressive exhaust note for truck and SUV applications. This complete cat-back system is engineered to maximize ground clearance while providing improved exhaust flow and that signature Flowmaster sound.

Key Features:

  • Crossmember-back configuration for comprehensive exhaust upgrade
  • Mandrel-bent 16-gauge aluminized steel tubing maintains consistent diameter for optimal flow
  • H-pipe crossover design balances exhaust pulses for maximum power and deep, aggressive tone
  • Moderate exterior sound level provides performance tone without excessive drone
  • Designed for maximum ground clearance to protect system during off-road use
  • Includes all necessary hangers and hardware for straightforward installation

This system is designed to work with your vehicle's existing manifold downpipes or headers. Manifold downpipes and header reducers are not included with this kit. The aluminized steel construction provides excellent corrosion resistance and durability, while the mandrel-bent tubing eliminates restrictions found in crush-bent systems. Perfect for enthusiasts seeking a balance of performance gains and aggressive exhaust tone.

Good product

Got exactly the product I wanted delivered as expected for the best price. It makes it hard to look elsewhere.

Good, but delivery time not on a par with other vendors.

Ordered what I was looking for, it arrived two days later.

Quick easy checkout, part fit guaranteed

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.

Thanks...hopefully they are shipped fast

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.

Satisfied with selection of parts. Pricing seems reasonable.

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.
