Product Details

The Dynatech 783-81245 is a high-quality steel slip-on header collector designed to merge multiple exhaust primaries into a single outlet for improved exhaust flow and performance. This collector features a durable steel construction with a painted finish to resist corrosion and provide a clean appearance.

Key Specifications:

  • Primary inlet size: 2.375 inches (accommodates standard primary tube diameter)
  • Outlet diameter: 4.5 inches
  • Overall length: 12 inches
  • Slip-on design for easier installation
  • Steel construction with painted finish
  • Merges multiple exhaust pipes into single collector outlet

This collector is ideal for custom exhaust fabrication and header installations where a transition from smaller primary tubes to a larger single outlet is required. The slip-on design allows for adjustment during fitment and can be welded in place for a permanent, leak-free seal.

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

very easy, thanks

Best price on the internet. A lot cheaper than amazon, so I was pretty surprised.

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!!
