Product Details

SLP is well-known for making performance exhaust systems that give vehicles a more aggressive sound and improved flow. This LoudMouth axle-back exhaust system is specifically made for the 2005-2008 Chevrolet Corvette with the LS2 engine. It's designed to replace the factory mufflers, giving your Corvette a deeper, more noticeable exhaust note without being overly raspy or droney.

This system uses SLP's LoudMouth mufflers, which are engineered to reduce back pressure and allow the LS2 engine to breathe more freely. The result is a more satisfying exhaust sound that lets everyone know you've got a Corvette under the hood. The system is constructed from durable stainless steel, ensuring it holds up well to road conditions and resists corrosion over time. Installation is designed to be a direct bolt-on replacement for your stock mufflers, meaning no welding or cutting is typically required, making it a straightforward upgrade for many owners.

When installing this axle-back system, you'll be bolting it directly to the existing exhaust pipes behind the mufflers. This setup is a popular choice for Corvette owners looking for a noticeable sound improvement that complements the car's performance without requiring a full cat-back system. You'll want to ensure you have basic hand tools and possibly some penetrating oil for stubborn factory bolts. The system comes with everything needed for installation, including the mufflers and any necessary hangers or clamps specific to this application.
