80mm Stainless Steel 200-Cell Metal Catalyst

The GReddy Sport Catalyzer offers enhanced exhaust efficiency by replacing the restrictive factory ceramic catalyst with a high-flow 200-cell metal catalyst. This upgrade is constructed from durable stainless steel and features a full 80mm (80Φ) diameter piping, ensuring a smooth, step-free flow when paired with GReddy mufflers and front pipes. The catalytic converter includes an exhaust gas report, confirming its conformity to safety standards. Key specifications include a 200-cell count, 80mm internal diameter, and a minimum ground clearance of 130mm. Fender height measurements are provided as Right front 657mm, Left front 658mm, Right rear 659mm, and Left rear 657mm, measured on a vehicle equipped with harmonic drive. This GReddy Sport Catalyzer is specifically designed for NISSAN SKYLINE GT-R models R34, R33, and R32 equipped with the RB26 engine. Additionally, it is compatible with the NISSAN Silvia GF-S15, specifically the Spec R grade from 1999.1 to 2002.11, fitted with the SR20DET engine. It's important to note that GReddy/GPP products are often sold for sanctioned off-road or competition-only use in non-emissions-controlled vehicles. Always check with local vehicle authorities before purchasing or installing.
