The Tanabe performance downpipe is designed to free up horsepower and decrease turbo spool up time by allowing exhaust gases to evacuate the engine more efficiently. The large diameter and smooth design ensures maximum flow and performance from your exhaust. Every Tanabe downpipe is constructed from high grade SUS304 stainless steel for maximum durability and weight savings. Tanabe downpipes include an EGT bung (where applicable) to ensure all OEM components will integrate seamlessly for a trouble free installation. Select downpipes include an EGT bung and cap giving you the option to easily install an EGT sensor at any time, should you want to monitor exhaust gas temperature.
