Product Details

The Hooker 16521HKR Header Back Exhaust System is engineered to maximize exhaust flow and engine performance through precision-mandrel bent construction. This complete cat-back system features 2-1/4" diameter aluminized steel tubing that resists corrosion while delivering long-lasting durability.

Key Features:

  • 2-1/4" mandrel bent aluminized steel tubing for consistent diameter throughout bends
  • Reduces backpressure to improve engine efficiency and throttle response
  • Mandrel bending process eliminates restrictions that plague crush-bent exhaust systems
  • Optimized exhaust flow increases horsepower and torque
  • Complete hardware kit included for straightforward installation
  • Detailed installation instructions provided
  • Aluminized steel construction offers excellent rust and corrosion resistance

This header-back system is designed to work seamlessly with aftermarket headers or stock manifolds, providing a cost-effective performance upgrade that enhances both sound and power. The mandrel bent design maintains smooth, consistent tubing diameter through all bends, ensuring maximum exhaust velocity and scavenging efficiency compared to traditional crush-bent systems.

They had the lowest price on the web and carried the part I needed. They used amazon. Heck out so it was super easy to place the order and the part shipped right away. Will definitely order from again.

Fast and easy transaction.

This is a great e-retailer. Best price and fast shipping. I ordered a bike rack. Their price was the lowest I could find, and it was drop shipped from the manufacturer the following day, and arrived in time for me to use it on the weekend. The one criticism I would have is the item description could have been better. From my web research, I knew the model I wanted, but if I was just browsing bike racks on their website, I would have needed more information.

Great service. Quick shipping!

Very easy!!

Website was easy to navagate and found just what I needed. By far the best price online with low shipping rates. Shipment arrived just two days after ordering. Will be ordering from Autoplicity again in the near future. Very pleased, Thanks!
