Aggressive Look of 8 Inch Exhaust Stacks for Custom Big Rig Trucks

Introducing 8 Inch Stack Kits for Big Rig Trucks

Truck drivers love customizing their rigs to give them a unique style and look. One popular customization is adding chrome exhaust stacks which rise above the cab of the truck. Truckers often opt for flashy 8 inch diameter stacks to make a bold statement.

What Are 8 Inch Stacks?

8 inch stacks (also called 8 inch pipers) are large diameter chrome exhaust pipes installed behind the cab of a semi truck. They provide a straight, vertical exhaust path for the truck's turbocharged diesel engine. The large diameter and shiny chrome finish of 8 inch stacks gives trucks an imposing, old school appearance.

Many truckers think 8 inch stacks look best on classic truck models like the Peterbilt 359, Kenworth W900L, and Freightliner FLD. The oversized stacks complement the imposing grille and large contours of these legacy trucks.

Benefits of 8 Inch Stacks

There are several reasons truckers love the look and performance of 8 inch exhaust stacks:

• Aggressive Look - The sheer size of 8 inch stacks gives trucks a rugged, aggressive appearance from every angle.
• Increased Exhaust Flow - The large diameter improves exhaust gas flow which reduces backpressure on the engine.
• Enhanced Turbo Sound - The rumbling turbo whistle is louder and clearer with 8 inch straight pipes.
• Custom Style - 8 inch stacks let truckers put their personal stamp on their rig.
• Improved Cab Air - Directing exhaust vertically reduces fumes swirling around the cab.

Choosing the Right 8 Inch Stack Kit

To make installation easy, most truckers opt for a complete 8 inch stack kit. Kits include all the necessary parts and hardware for a professional looking setup:

• Two 8" diameter stacks in the desired length and finish
• Stack mounting brackets to attach to the frame or catwalk
• Chrome or stainless steel band clamps
• Tailpipes to connect the stacks to the exhaust
• All mounting hardware

The most important choice is the length of the stacks. Popular options include:

• 26 inch - Rises just above roof level for a clean factory look
• 36 inch - Great for custom show trucks
• 48 inch - The most common length for 8 inch stacks
• 60 inch - An aggressive length reserved for extreme builds

Finish is also important. Polished stainless steel and chrome are classic choices. Black powdercoated or ceramic coated stacks also look great on dark colored trucks.

Installing 8 Inch Stacks

To install 8 inch stacks properly:

1. Choose mounting locations that keep the stacks vertical and aligned.
2. Fabricate steel brackets to attach stacks securely to the frame.
3. Run tailpipes from the exhaust manifold back to the stack location.
4. Use a level to keep the stacks vertically plumb during installation.
5. Attach the stacks to the tailpipes using band clamps.
6. Seal all connections to prevent exhaust leaks.

Stacks must be mounted very securely to withstand highway vibration and wind resistance. Rubber insulators help isolate vibration.

Maintaining Your 8 Inch Stack Kit

With proper care, an 8 inch stack kit will last for years:

• Keep connections tight to avoid leaks
• Clean regularly with chrome polish to prevent corrosion
• Check mounting brackets periodically for loose bolts
• Remove scratches with wet sanding and buffing
• Avoid pressure washing which can damage the chrome

Replace damaged or rusted parts right away. Properly maintained stacks will continue looking great season after season.
