What is included with the S&S Cycle Grand National Slip-on Muffler?

The S&S Cycle Grand National Slip-on Muffler includes the muffler itself. Mounting hardware and any necessary adapters for installation are typically included, but it's always best to check the manufacturer's packing list to confirm all components.

Will this muffler require any modifications to my Indian Scout's exhaust system?

No, this is a slip-on muffler designed to directly replace your stock muffler. It is intended to fit onto the original headpipe without requiring modifications to your existing exhaust system.

What kind of sound can I expect from this muffler?

This muffler is designed to provide a more aggressive sound compared to the stock unit. The race-inspired perforated core contributes to a deeper, more resonant exhaust note that is characteristic of S&S Cycle performance mufflers.

About this part

Product Details

The 4-inch diameter Grand National muffler from S&S Cycle is built with a stainless steel baffle and a race-inspired perforated core, designed to give your Indian Scout a more aggressive sound and improved exhaust flow. This slip-on muffler is a direct replacement for your stock unit, making installation straightforward without needing to modify your existing exhaust system. It's a well-built piece that offers a noticeable change in both the look and the auditory character of your motorcycle.

Crafted with a durable chrome finish, this muffler not only looks sharp but is also built to withstand the elements. The Grand National design is a popular choice for riders looking to enhance their Scout's performance and style. The internal construction, featuring that race-inspired perforated core, helps to reduce backpressure, allowing your engine to breathe more freely. This can lead to a more responsive throttle and a deeper, more resonant exhaust note that's distinctively S&S Cycle.

When installing this slip-on muffler, you'll find it fits right onto the stock headpipe, simplifying the process. While it's designed as a direct fit, we always recommend referring to the manufacturer's installation instructions for any specific details or torque recommendations. This muffler is a solid option for any Indian Scout owner looking to make a significant, yet accessible, upgrade to their exhaust system.
