Product Details

The Flowmaster American Thunder Crossmember-Back Exhaust System is engineered to deliver enhanced performance and an aggressive exhaust note for your vehicle. This comprehensive system features mandrel-bent stainless steel tubing that maximizes exhaust flow while maintaining excellent ground clearance for daily driving and off-road use.

Key Features:

  • 80 Series Cross-Flow Performance Muffler for moderate exterior sound and reduced interior resonance
  • H-pipe crossover design balances exhaust pulses for maximum power gains and deep, rich tone
  • Mandrel-bent stainless steel tubing maintains consistent diameter for optimal flow
  • Stainless steel construction resists corrosion and ensures long-lasting durability
  • Crossmember-back design allows for straightforward installation without removing entire exhaust system
  • Includes all necessary hangers, clamps, and hardware for bolt-on installation
  • Maximum ground clearance maintains factory ride height and approach angles

Backed by Flowmaster's Lifetime Limited Warranty, this American Thunder system delivers the perfect balance of performance gains and that signature Flowmaster sound without excessive drone. The complete bolt-on kit is designed for enthusiasts who want professional results with a weekend installation.

So far all is good.

This is the first time I ordered from Autoplicity. Very good experience overall. The prices are the best I can find anywhere online. It was shipped very quickly, and I received my item just in time before my trip. Thanks!

Very fast shipping and good cutomer service

site has a lot of parts and accessories. Good prices. Just needs a better way to narrow searches down more.

Awesome price! Shipping could be faster, but it was fast enough. Will deff buy again.

Best prison the Internet and quick order fulfillment. Glad to have found Autoplicity!

Ordered 4 race ramps flatstoppers for winter storage of my Dodge Viper. Product prevents flat spots on auto tires that are stored more than 30 days. Order process was extremely easy, product was promptly shipped. I'll definately do business with Autoplicity in the future.

Very please with first buying experience with Autoplicity! Not only did they have the best price, I promptly received the following e-mail message the next day after I ordered.<br><br>Hello brian willard!, <br>Good news! You order has been shipped. <br>Order Number: 1412<br>Order Details: http://autoplicity.com/orderdetails.aspx?orderid=1412<br>Date Ordered: Wednesday, December 21, 2011<br>Tracking Number: 1Z4XR0770346534081

The best price found on the net for an Airtex fuel pump. Fast shipping via UPS. Received 08/09/2012<br><br>Autoplicity is now in my favorites. Order Number: <br>Ray J.

Shipped out fast. Prices are very competitive. Couldn't ask for more.

Best prices I could find on bug shields and rain guards!
