Upgrade or adapt your exhaust system with the AP Exhaust 8962 reducer coupler, designed to connect 3.5 inch outside diameter exhaust tubing to 3 inch inside diameter tubing. This coupler features a 3.5 inch inside diameter on one end to slip over 3.5 inch OD pipe, and a 3 inch outside diameter on the other end to slip into 3 inch ID pipe, creating a secure step down connection. The smooth tapered transition helps maintain proper exhaust flow and reduce turbulence between pipe sizes. Constructed from durable aluminized steel, it offers good resistance to heat, corrosion, and road conditions for long lasting performance. Ideal for exhaust repairs, custom fabrication, and performance upgrades, this reducer can be welded or clamped in place for a strong, leak free joint. Please verify your pipe sizes before purchasing to ensure proper fit.
