Product Details

The Flowmaster 817139 American Thunder Crossmember-Back Exhaust System delivers a moderate to aggressive exhaust tone with true dual exhaust performance. This complete bolt-on system is engineered from mandrel-bent 16-gauge stainless steel tubing for maximum flow and durability.

Key Features:

  • True dual crossmember-back exhaust configuration for improved exhaust flow
  • Mandrel-bent 16-gauge stainless steel construction resists corrosion and maintains consistent diameter throughout bends
  • Super 44 Series mufflers provide a deep, powerful, aggressive sound
  • H-pipe crossover balances exhaust pulses for maximum power gains and enhanced deep tone
  • Stainless steel exhaust tips exit in factory location for clean, OEM-style appearance
  • Includes all necessary hangers and hardware for straightforward installation
  • Backed by Flowmaster's Lifetime Limited Warranty

This system is designed as a direct fit replacement that bolts to your factory manifold downpipes. Note that header reducers and factory manifold downpipes are not included with this kit. The combination of premium stainless steel construction and Flowmaster's legendary Super 44 muffler technology makes this an excellent choice for enthusiasts seeking enhanced performance and an aggressive exhaust note.

California Proposition 65

I searched the entire web looking for the best price on my item and found that Autoplicity beat everybody else in price & quality. Search no more!

Ordered EBC brake rotors on Tuesday afternoon and received notification on Thursday morning that they have already been shipped. Fast order processing and a low price, what more could I ask for? When I need to do the front brakes, I will be coming here first.

Best price I could find on the net and super fast shipping.

Autoplicity had the best price on the VP fuel jugs, I ask if the could ship them out quickly and they did.

I ordered a new battery for my Harley. I wanted a battery that would last and be of good quality. I bought a Odyssey PC545 battery it stats stat it will last up to 8 years and is military grade. My package arrived quick and in good shape. My order number is #5600. Thanks

i was skeptical about this site but after reading the reviews and them having the lowest price i could find for my part i pulled the trigger and wasn't disappointed. fast shipping and low prices with great customer service will shop with them again if they have what im looking for.

I placed an order,18852,for a Husky Liner on June 19th and received it on June 21st. They have a great price and low cost shipping.

Quick shipping, good communication, low price, would purchase again from this company.
