Our take on the Hooker 12310HKR Exhaust Pipe Adapter

The Hooker 12310HKR is a Super Competition 180-degree mandrel U-bend made from 16-gauge mild steel. It has a 4-inch outside diameter, a 7.5-inch centerline radius, and two 6-inch legs, so it works as a tight-radius turn in a custom exhaust system. Mandrel bending keeps the tube diameter constant through the curve, which matters for flow on high-output engines. It suits fabricators and racers building or repairing a large-diameter system, but it is a single mild-steel bend, so stainless and aluminized versions of the same line resist corrosion better.

Questions and answers

Is this a direct bolt-on part?
No. It is a bare U-bend meant to be cut and welded into a custom exhaust. No clamps, flanges or hardware are included.
What does 4 in. OD mean here?
The tube's outside diameter is 4 inches. Check your system's pipe size before ordering, since this is a large-diameter bend.
Mild steel or stainless?
This one is mild steel. Hooker also lists stainless and aluminized versions of the same U-bend, which hold up better against rust.
How tight is the bend?
The centerline radius is 7.5 inches, and each leg is 6 inches long. That gives a fairly tight 180-degree turn you can trim to length.
Can I use it on a daily driver?
It can work, but mild steel needs paint or coating to resist corrosion on a street car. Aluminized or stainless is the better long-term choice.
Where is the Hooker 12310HKR Exhaust Pipe Adapter cheapest?
At Walmart, for $33.95, as of our latest check.
