Product Details

The Flowmaster American Thunder Crossmember-Back Exhaust System delivers dyno-tuned performance with an aggressive exhaust note that stands out from the crowd. This complete cat-back system is engineered for enthusiasts who demand maximum horsepower and torque gains along with that unmistakable Flowmaster sound.

Key Features:

  • Super 50 Series performance mufflers engineered to eliminate drone while maintaining aggressive tone
  • Mandrel-bent 16-gauge aluminized steel tubing maintains consistent exhaust flow for maximum power
  • H-pipe assembly included for improved exhaust scavenging and balanced sound
  • Polished 3.00-inch stainless steel tips provide a premium appearance
  • Moderate to aggressive exterior exhaust tone delivers true muscle car sound
  • Complete hardware kit with hangers included for straightforward bolt-on installation

This American Thunder system is dyno-tested to optimize power delivery across the RPM range while maintaining excellent drivability. The precision mandrel-bent tubing eliminates restrictive crush bends found in factory exhaust systems, allowing your engine to breathe freely and produce more power. The Super 50 Series mufflers use Flowmaster's patented technology to deliver that classic performance sound without the annoying interior drone during highway cruising.

I ordered a black bull bar for my Tacoma and for the price of $127, I couldn't pass up on it because it would have costed me $170 elsewhere. Overall, it shipped in 3 days, great product, great price ... thinking of shopping again!

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.

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

Great customer service. Good price. Quick shipment. Would definately reccomend this company.

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.
