ISR Performance Stainless Steel Downpipe - Nissan R34 25GTT RB25DET

The ISR Performance Stainless Steel Downpipe for the R34 25GTT (RB25DET) is a 3" stainless direct OE replacement. Two-door coupes only. Designed to bolt in where the factory downpipe came out without fabrication, freeing up the standard flow restriction the OEM downpipe creates.

What It Does

The factory R34 25GTT downpipe is the typical flow restriction you'd expect from an OEM unit. Stepping up to a 3" stainless one-piece downpipe opens up the turbine discharge path and gives the RB25DET room to breathe. Direct OE replacement with the included gaskets and hardware. no fabrication required for a clean swap.
