Part Number: 720595373708

Upgrade the exhaust flow and boost control performance of your turbocharged DSM setup with this Bull Boost Performance stainless steel turbo O2 housing. Designed for the legendary 4G63 platform, this high-flow turbo outlet solution improves exhaust efficiency while helping reduce boost creep commonly found in factory turbo systems.

Constructed from high-quality stainless steel with precision TIG welding, this O2 housing is built to withstand high exhaust temperatures and harsh turbocharged driving conditions. The dual-outlet design promotes smoother exhaust flow and improved wastegate discharge efficiency, helping maintain more stable and consistent boost control.

Featuring heavy-duty 1/2" thick flanges and a pre-installed TIG-welded O2 sensor bung, this unit is engineered for reliable sealing and long-term durability. Designed as a direct bolt-on upgrade, it works with both stock and aftermarket downpipes and turbocharger setups without requiring aftermarket cooling modifications.

This upgrade is ideal for DSM enthusiasts looking to improve turbo response, exhaust flow, and overall boost stability on street or performance builds.
