Product Details

Doug's Headers D570 long tube headers are engineered to deliver maximum performance and durability for high-performance applications. These headers feature precision CNC mandrel bent tubing that maintains consistent diameter throughout each bend, ensuring optimal exhaust flow and minimizing restrictions that rob horsepower.

Key Features:

  • 3/8" thick machined flanges resist warping and ensure leak-free sealing even under extreme heat cycling
  • CNC mandrel bent tubes provide accurate fit and superior flow characteristics compared to crush-bent alternatives
  • Precision formed long transition collectors with extended tube design reduce backpressure and maximize high-RPM horsepower gains
  • Heavy-duty 16-gauge steel tubing construction for long-lasting durability and performance
  • Long tube design optimizes exhaust scavenging for improved engine efficiency

These headers are designed for enthusiasts seeking reliable performance gains with professional-grade construction quality. The combination of thick machined flanges and heavy-gauge tubing ensures these headers will perform consistently under demanding conditions.

I have looked for this product many times but was disappointed<br>in the price. could not beleive the price at Autoplicity. thank <br>you very much keep up good work Ray

I ordered the HuskyLiners 98891 Floor Liners for my 2012 Hyundai Elantra on 5/29, received them 5/31. Order #15417. Apparently they have warehouses all over the country to ensure quick delivery. They had the best price on the net. Item arrived in perfect condition. <br><br>Their website needs a little work because I found the item thru Google and not directly from their website. You also can't edit your cart unless you register first which was annoying. Items could use product descriptions - you have to get info from the manufacturer's site. The real-time inventory was a plus.<br><br>Deducted a star because their website needs work.

Bought some wire looms for my Chevy from them. Great price, service, and shipping speed!

We looked a lot of places online for the steering stabilizer for our vehicle. We priced and looked to find out who had the best product and fastest shipping. We were so glad that Autoplicity was able to have just what we needed. We highly recommend that you visit autopicity.com for all you vehicle needs and we thank Autoplicity for their expediency in getting us our stabilizer.

Good prices, fast shipping, A+

After checking amazon, ebay, various other general and specialty online parts suppliers and local brick and mortar supply houses, Autoplicity's was hands down the best overall (price + shipping) price for the product.

Product was a good price, fast shipping and great costumer service! will do business again!

Best price I could find on the web and great easy to use website. Fast shipping, I am overall very satisfied thanks Autoplocity!
