Description
The CARGRAPHIC Longtube Manifold Set with 200cpsi HD Tri-Metal catalytic converters is engineered for maximum power gains, freer exhaust flow, and sharper throttle response. Designed with 2" equal-length primaries and a high-efficiency racing-style collector, this manifold system delivers increased performance, torque, and sound without compromising OBD2 compliance.
This system is a direct replacement for factory manifolds and works seamlessly with OEM or CARGRAPHIC exhaust components. Manufactured from SS304L lightweight stainless steel, it ensures durability, precision fitment, and a true motorsport sound experience.
