Show original supplier description
Constructed from durable SUS304 stainless steel, it features an 80-80mm pipe size for optimal exhaust flow. This unit is a direct replacement for restrictive factory catalytic converters, aiming to improve exhaust flow and overall engine performance. It is compatible with numerous Nissan models, including the Silvia (S14, S15), 180SX (RPS13), and Skyline (HCR32, ECR33, BNR32, BCNR33, BNR34) equipped with turbo engines. Specific fitment details include compatibility with the SR20DET engine for the Silvia and RPS13, and the RB25DET engine for the ECR33 Skyline. The product is also noted to fit 5-speed manual transmissions for the S14 and RPS13, and 6-speed manual for the S15. However, this catalytic converter has specific fitment exclusions. It is not compatible with HICAS systems on CS14 models and will not fit V36 Skylines due to different pipe layouts. It is exclusively for turbo vehicles.
