Show original supplier description
The Tomioka Racing Twin Scroll High Flow Catless Downpipe is constructed from SUS304 stainless steel, featuring a 0.25-inch pipe wall thickness and a 0.5-inch flange thickness for durability and performance. Designed as a direct bolt-on replacement for the 2002-2007 Subaru WRX (EJ20/EJ255 MT) and 2004-2007 Subaru STI (EJ207 MT) models equipped with twin scroll turbo setups, this downpipe is for off-road use only due to its catless design and is not street-legal in emissions-regulated areas. It is specifically for twin scroll turbo use and is not compatible with single scroll setups. Installation is intended to be a straightforward bolt-on process, matching factory connection points. The downpipe includes a downpipe to exhaust gasket and necessary nuts and bolts. Please note that this product has a significant lead time, with expected shipping dates approximately 4 months from the order placement. It is the USDM length and does not fit JDM Subaru Legacy twin scroll turbo models. It is also not compatible with EJ20X/Y engines.
