Product Details

Doug's Headers D381-C side mount exhaust headers are engineered for big block Chevrolet engines, delivering improved exhaust flow and performance gains. These headers feature a durable steel construction with a chrome finish that provides both corrosion resistance and a classic show-quality appearance.

Key Features:

  • Round port design optimized for big block Chevy cylinder heads
  • 4-inch diameter collectors for maximum exhaust scavenging
  • Side mount configuration for chassis clearance
  • Chrome-plated steel construction for durability and appearance
  • Sold as a pair for complete engine installation

These headers are designed to replace restrictive factory manifolds, reducing backpressure and unlocking additional horsepower and torque. The side mount design provides clearance in tight engine bays and allows for easier installation in many applications. Doug's Headers uses quality materials and precise mandrel bends to ensure proper fitment and long-lasting performance.

first time ive order from here and my experience was great! shipping was crazy fast. and they had the best price shipped on the 2jz arp head stud set i could find. also how on their site they actually list if they have the part in stock and how many which is very helpful. ive payed for parts to find out the vender didn't even have them available. which lead to more down time. and we all hate down time :)

I ordered an Optima battery for my truck after I did a Google search for the battery. Autoplicity was the cheapest on the Web. Even cheaper then eBay. They got me hooked. Thanks Autoplicity

This is the first time I've ordered from Autoplicity. I found they had the best price on the item I was looking for and decided to try them. I ordered this item yesterday(Sunday) and was just informed that it shipped. That is quick. I am pleased with their customer service and will use them as my first source.

Ordered a CTEK charger. Great price, and recieved it in 3 days. Very pleased.

I ordered a Flowmaster cat back system for my 2012 F-150. The order arrived the day they said it would and the product came at a fair price. Well done.

Excellent customer service. Treated me very well. Issued a refund, no problem. Thank you!!

I purchased a Smittybuilt Smart Truck Cover for a 2011 Tundra. Service and delivery were quick and easy, and quality of the product is excellent. I will be using Autoplicity for future auto parts purchases.<br><br>Ben D.
