Weapon R 3.5in x 4in x 3in Tall Coupler Adapter - Silver

When you're modifying your exhaust system, sometimes you need a specific adapter to connect two different-sized pipes. This coupler from Weapon R is designed to bridge the gap between a 3.5-inch pipe and a 4-inch pipe, measuring 3 inches in length. It's a straightforward piece that helps you achieve the custom exhaust setup you're aiming for.

This adapter is made from aluminum, keeping the weight down on your exhaust system. It's a simple, well-built component that gets the job done for custom exhaust projects. Just slide it over the smaller pipe and clamp it down to the larger pipe for a secure connection.
