MagnaFlow 11 Buick Regal L4 (Excl. GS Model) Dual Split Rear Exit SS Cat-Back Performance Exhaust

This MagnaFlow Street Series cat-back exhaust system is made specifically for the 2011-2017 Buick Regal with the 2.0L engine, excluding the GS model. It's designed to replace your stock exhaust from the catalytic converter back, giving your Regal a more aggressive, resonant engine tone and improved performance that you can feel. You'll notice a moderate exterior sound level, with a mild interior presence, making it noticeable without being overwhelming.

The system features fast-flowing, mandrel-bent 2.5-inch main piping that leads to three straight-through mufflers. It exits through a dual split rear setup with polished, double-wall, straight-cut, rolled-edge tips that measure 3.5 x 5.5 inches. This design isn't just for looks; it's engineered for dyno-proven performance gains. MagnaFlow uses extensive 3D scanning during development to ensure a direct-fit design, meaning it should install without major modifications. The construction uses CNC precision robotic manufacturing techniques, and the entire system is built from durable, corrosion-resistant stainless steel.

This cat-back system is a solid choice if you're looking to give your Regal a sportier sound and a performance edge. It includes everything from the mufflers back to the tips, ready to bolt on. MagnaFlow backs this system with a 1-year limited finish warranty and a limited lifetime construction warranty.
