ISR Performance expands its exhaust lineup with the ST Series Catback Exhaust, designed specifically for the 2019–2022 Toyota Corolla Hatchback.
Constructed from mandrel-bent stainless steel, the system is built to deliver long-term durability while maintaining consistent exhaust flow. The dual-exit, dual-muffler configuration is engineered to produce a deep and aggressive exhaust note, making it a strong option for naturally aspirated applications looking for more presence across the entire power band.

Built for Sound and Fitment
The ST Series exhaust features precision TIG welding and a polished stainless steel muffler finish, combining durability with a clean, performance-focused look. The system utilizes 2.5-inch piping paired with dual 4-inch polished exhaust tips, giving the Corolla Hatchback a more aggressive rear profile.
Due to the larger tip size, the factory rear diffuser will require removal, modification, or replacement. Aftermarket diffusers with larger openings have been tested and confirmed to fit this system.
