Product Details

The Flowmaster American Thunder Crossmember-Back Exhaust System delivers aggressive sound and maximum performance through a true dual exhaust design. This complete cat-back system is engineered for enthusiasts seeking a deep, powerful exhaust tone with proven horsepower gains.

Key Features:

  • True dual exhaust design with large 3-inch mandrel-bent tubing for optimal flow
  • Super 40 Series performance mufflers produce a deep, aggressive exterior tone
  • H-pipe crossover balances exhaust pulses for maximum power and rich sound
  • Constructed from durable 16-gauge aluminized steel tubing for long-lasting performance
  • Includes all necessary hangers and hardware for straightforward installation
  • Crossmember-back design allows use with stock manifolds or aftermarket headers

Mandrel-bent construction maintains consistent pipe diameter throughout the system, eliminating restrictions and maximizing exhaust flow. The H-pipe configuration merges exhaust streams to create balanced backpressure and that signature muscle car sound. Backed by Flowmaster's 3-year limited warranty. Note: Header reducers and factory manifold downpipes are not included and must be sourced separately if needed.

Good

Autoplicity had the item I wanted at a cheaper price than anybody online or in stores. They didn't have the item in stock, but they were very informative as to the status of my item. They have shown unheard of customer service via email since the inception of my order. I will definitely do business with them again.

Thank you

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.

Autoplicity got my air filters shipped next day after I placed my order. Cheap prices, and good customer is what they stand for. I will definitely be looking at their site in the future for my car needs. <br>

Processed and shipped fast. I was a little upset with them shipping my Eibach springs in the Eibach box, and not repackaging it. Everyone could see the box, and knew what was in it. But this will not stop me from ordering again.
