Exhaust Manifolds & Headers for Buick LS Swaps

Questions About Buick Exhaust Manifolds & Headers

What’s the difference between headers and exhaust manifolds?

Headers are designed to improve exhaust flow by reducing back pressure and allowing each cylinder to have its own exhaust pipe. Manifolds are more compact and typically used for tighter engine bays but offer less performance improvement compared to headers.

Do I need headers or manifolds for my Buick LS swap?

It depends on your performance goals. If you're looking for maximum power gains and improved exhaust flow, headers are the better option. For a more compact solution that fits easily into tight spaces, manifolds might be the best choice.

What are the benefits of using stainless steel headers for my Buick?

Stainless steel headers are more resistant to corrosion, handle heat better, and generally last longer than other materials, making them ideal for performance applications.

How do I choose between block hugger headers and long-tube headers for my Buick?

Block hugger headers are ideal for tight engine compartments and offer a more compact solution, while long-tube headers provide better exhaust flow and performance but may require more space.
