Subaru has always been unique with their power plant layout; their opposed 4-Cylinder engines lay flat and have a complex exhaust system. This was ideal for performance and space savings and made an amazing sound. However, emissions came in and Subaru placed a very restrictive Catalytic Converter before the turbocharger which drastically slowed down the velocity of the exhaust gases and put a damper on performance and turbo spool time.
Megan Racing has developed an Up-Pipe which eliminates the Catalytic Converter before the Turbocharger. This allows the exhaust gases to retain their velocity as they enter the turbocharger and spool the turbo quicker for a noticeable drop in boost lag.
Constructed of T-304 Stainless Steel, this light weight replacement pipe is 2” in Diameter and features a 3” Flex-Section that reduces stress on the exhaust system and the tendency to crack under heavy-duty loads and extreme conditions.
The Up-Pipe also has the bung w/ cap for the OEM EGT sensor and is a Direct Bolt-On for the 2002-05 Subaru Impreza WRX and STi. Please note that this product like all Megan Racing exhaust products were designed for OFF-ROAD USE ONLY and may not be emissions legal in your state. Please check local laws and regulations before ordering.
