BULL BOOST PERFORMANCE TD04 5-Bolt Turbo Downpipe Flange to 2.5" V-Band Conversion Adapter for Subaru WRX Saab

Part Number: 43407535505660

Upgrade your turbo exhaust setup with this Bull Boost Performance TD04 5-bolt to 2.5" V-band conversion adapter, designed to simplify and improve the connection between your turbocharger and downpipe system. This precision-engineered adapter converts a traditional TD04 5-bolt turbine outlet into a modern 2.5" V-band exit, allowing for a stronger, more secure, and leak-resistant exhaust connection.

Built from high-quality materials including 304 stainless steel for the V-band assembly, this adapter is designed to withstand high heat, pressure, and long-term performance use. The rigid flange design ensures a tight seal at the turbo outlet, while the V-band conversion allows for quicker installation, easier maintenance, and improved exhaust flow characteristics compared to traditional multi-bolt downpipe setups.

This adapter is ideal for builders looking to modernize older Subaru TD04 turbo systems or simplify downpipe integration on performance builds.
