304 Stainless Steel Exhaust Up-Pipe

The Lachute Performance Up-Pipe is engineered as a direct, high-performance replacement for the OEM pipe in Subaru EJ engines, addressing known flow restrictions caused by the stock geometry. The factory up-pipe's design often creates exhaust flow bottlenecks, leading to increased turbo lag. This performance-oriented replacement features a smoother, optimized bend to ensure unobstructed exhaust flow to the turbocharger. This results in quicker turbo response, improved efficiency, and overall enhanced engine performance. Constructed from durable 304 stainless steel tubing, the up-pipe measures 2" in diameter and has a wall thickness of 1/8". It is fitted with precisely laser-cut stainless steel flanges for a secure and reliable connection. This up-pipe is designed to fit all EJ Engines, including the Subaru Impreza WRX from 2002-2014 and the Subaru Impreza WRX STi from 2004-2021.
