ISR Performance GT Single Exhaust - Toyota GR86 / FRS / BRZ

ISR Performance is known for making well-built exhaust components that offer a noticeable improvement in sound and performance for sports cars. This GT Single Exhaust system is a prime example, specifically designed for the Toyota GR86, Scion FRS, and Subaru BRZ. It replaces the factory cat-back section, aiming to give your car a more aggressive exhaust note and potentially free up a little horsepower by reducing backpressure.

This system is constructed from durable stainless steel, which is a solid choice for exhaust components because it resists corrosion and holds up well to the heat cycles your exhaust system goes through. The single muffler design is often chosen to save weight compared to dual muffler setups, and it typically produces a more focused, deeper tone. The GT muffler itself is designed to provide a balance between an aggressive sound when you're on the throttle and a more manageable tone during everyday driving. Installation is designed to be a direct bolt-on replacement for the stock exhaust, meaning no welding or cutting should be required, making it a straightforward upgrade for most DIYers.

When installing this exhaust, you'll want to ensure you have all the necessary hardware. While this cat-back system is designed to bolt up to the factory connection point, it's always a good idea to inspect your existing exhaust hangers and connections for any signs of wear or damage that might need addressing during the installation. This system is a popular choice for GR86, FRS, and BRZ owners looking to give their car a more distinct sound and a sportier appearance.
