Product Details

The Hedman Hedders X-Tension Exhaust Pipe Extension Kit is designed to virtually eliminate header hook-up issues by providing additional length and clearance for custom exhaust installations. These extensions feature an S-bend design that allows you to route exhaust pipes around chassis components, transmission crossmembers, and other obstructions that commonly interfere with header-to-exhaust connections.

Key Features:

  • S-bend configuration provides critical clearance around frame rails and crossmembers
  • Constructed from 20-gauge mild steel for durability and easy welding
  • Sold in pairs for complete left and right side installation
  • Simplifies header installation on vehicles with tight exhaust routing
  • Ideal for street rods, muscle cars, and custom applications requiring exhaust modifications

These X-Tension pipe extensions are perfect for solving fitment challenges when installing headers on modified vehicles or applications where the stock exhaust configuration has been altered. The mild steel construction allows for easy cutting, fitting, and welding to achieve the perfect custom exhaust setup.

To all of you great job.

Easy to order, now just wait for product.

Easy to use site and best price I could find!!!

great service

So far so good

Great Price fast shipping, I can't complain.

Great transaction. The bike rack was about $90 less than a local retailer, and shipping was faster than promised. I wish all internet retailers were this reliable and useful.

It was easy to order and the truck bed extender we bought was the lowest price we could find! However, the shipping charge was higher than what was posted on the comparison sight. Nevertheless, it still came in under the next highest price from a different vendor.

Good first shopping experience on your web site.

Order arrived quickly and was exactly as described. Great prices and service!

Was going to also order TCI-618008 with this purchase but the free shipping didn't apply? Just thought you could add it to the same free shipping box.

Very fast shipping and price is rite

Fast service, great prices, highly recomended retailer.
