*For Existing Twin Scroll Turbo and Twin Scroll Exhaust Manifold Setup.*

The Tomioka Racing TR-ES1006 Subaru WRX/STI Twin Scroll High Flow Catless Downpipe is designed for 2008-2014 Subaru WRX and 2008-2021 Subaru STI models with an existing twin scroll turbo and twin scroll exhaust manifold setup.

This high flow catless downpipe features larger diameter piping and ported flanges to support quicker and faster exhaust airflow compared to the standard OEM downpipe. It is constructed from SUS304 stainless steel for long-lasting durability and a clean finish.

TR-ES1006 is a USDM-length downpipe designed to work with the USDM stock cat back exhaust system. Please note that while it is designed for USDM stock cat back fitment, we cannot guarantee fitment with every aftermarket cat back or special application. If your exhaust setup requires a different length, minor modification may be needed and can be done by most muffler shops.

For installation, the turbo-to-downpipe gasket is sold separately and is not included with the downpipe. The downpipe-to-exhaust gasket and downpipe-to-exhaust nuts and bolts are included.
