How do you make a Cummins Hood stack?” is a common question among many people.

In this guide, we will discuss two processes regarding stacking the exhaust pipe on the 2nd generation Dodge Cummins truck. Check below to know the details.

First Process

In this process, you will need a 90* section of pipe and a 3.5 inches flange. Then, use a v-band clamp to fasten it to your vehicle’s turbo exhaust flange. Also, make it sufficiently long, so it goes into the hood from 2 to 3 inches.

Then, you have to fabricate the 5 inches or 6 inches pipe and attach it to the hood. Hood stacks are generally 2 piece units. The portion sticking out of the hood is decoration and is just an extension.

Second Process

You will need a stack 90*, an elbow, a 4-5 inches adapter, 4 and 5 inches exhaust clamp and a turbo flange lip in this process. The stack 90* will cost you $50, the elbow’s price is $20, the adapter will cost you $14, both exhaust clamps will cost you $10 each, and the turbo flange lip’s price is $10.

First, you need to route the 90* elbow with flange into the 4-5 inches adapter by welding it. Then, you have to crank down the exhaust clamps. Now, climb right up on your hood and cut it by using a circular saw or plasma cutter. Make sure that you cut a sufficiently large hole to clear the stack once the hood is completely open.

After that, mount your stack to your vehicle’s turbo and then crank down the v-clamp by holding them together. Make sure that your hood hole is cut sufficiently large to clear the stack during opening and closing. The next step is to give the hood stack a fresh coat of paint. After the paint dries, you are required to put the hood stack in the hood hole and crank everything down.
