Description

The ISR Performance Stainless Steel Bell Mount Downpipe is engineered to enhance exhaust flow in the Nissan Skyline R32 and R33 GTST models. This 3" one-piece unit replaces the restrictive factory downpipe, bolting directly to the turbocharger to facilitate a more efficient exhaust gas path. By increasing the diameter and smoothing the transition, this downpipe allows the engine to expel exhaust gases more freely, leading to potential horsepower gains and improved engine performance. Constructed from durable stainless steel, the Bell Mount Downpipe is built to withstand the rigors of performance driving. It comes with all necessary hardware for installation, including a 6-bolt exhaust gasket, a 2-bolt 3" exhaust gasket, bolts, and nuts, ensuring a comprehensive replacement solution. It will not fit with swapped Left-Hand Drive (LHD) vehicles. Additionally, a customer review mentioned that this downpipe also fits the WCGC34 Stagea, simplifying its exhaust setup.
