Product Details

The Diamond Eye Manufacturing 400031 is a precision-engineered exhaust adapter designed to connect exhaust components of different diameters. This adapter features a 3-inch inner diameter (ID) that expands to a 3-13/16-inch (3.813-inch) outer diameter (OD), allowing it to fit securely inside 4-inch OD exhaust tubing.

Key Features:

  • 3-inch ID to 3.813-inch OD stepped design for secure fitment
  • Constructed from durable aluminized steel for corrosion resistance
  • Designed to fit inside 4-inch OD exhaust tubing
  • Precision-manufactured for proper sealing and alignment
  • Ideal for custom exhaust fabrication and repairs

This adapter is commonly used in custom exhaust system installations where different diameter pipes need to be joined, or when adapting aftermarket exhaust components to existing systems. The aluminized steel construction provides excellent durability and heat resistance for demanding exhaust applications.

A very satisfactory experience. The price I paid was the lowest I found on the internet for this product. Ordering was easy, and without hassle. My order was shipped promptly and arrived sooner than I expected. Order date to receipt was only 6 days

The fellas at Autoplicity where great, very proffesional, and great price as well. I will definately be using them again. ohh, and super fast shipping... thank autoplicity...

Good

Very easy to use. Like the association with amazon.

AMAZING SERVICE! I received the parts the next day! Love it, good products, great quality, amazing price. Customer service responded within minutes of me sending an email with questions.<br><br>GOOD JOB GUYS!

Great Prices!

I ordered my K&N cold air intake order number 17133<br>From autoplicity for almost half price compared to other sites online. I will continue my purchases here n stop my searches elsewhere. And delivery time is fast!

I hope your an accredited company. Seems to good to be true.

your prices on this order where 31.00 lower then the best price I got elsewhere ( with shipping incl ). gotta love it. I'll be back

Stuff I was looking for was easy to find and checkout was easy. All parts were for the vehicle i selected and fit perfectly.

I'm a little concerned. The Fabtech part number doesn't match the correct description. I need the impact tube rear mount not the bushing kit. I talked to a representative and he said if I used the Fabtech number I would get the correct part.

Lowest price on the net for what I purchased and received it within 3 days of placing order. Great website, great prices, & reasonable shipping charges.
