The ISR Performance ST Series Exhaust is a cat-back exhaust system constructed from mandrel-bent stainless steel to ensure maximum flow, reliability, and long-term durability. Featuring a dual-exit, dual-muffler design, this system produces a deep, powerful exhaust note that remains aggressive throughout the entire RPM range.

Engineered for both naturally aspirated and forced induction setups, the ST Series exhaust enhances sound without sacrificing drivability. Precision TIG-welded stainless steel construction and a brushed stainless muffler finish ensure consistent quality and resistance to corrosion, while the polished 4-inch exhaust tips provide a clean, performance-inspired appearance at the rear of the vehicle.

Whether you’re building a street-focused car or a performance-driven setup, the ISR ST Series exhaust delivers the sound and quality enthusiasts expect.
