2001-2005 Lexus IS300 Performance Header Stainless Steel
Stainless steel header engineered to improve exhaust scavenging and flow on the IS300. Built from corrosion-resistant stainless construction to withstand heat cycles and road conditions. Direct bolt-on design integrates with your existing exhaust system.
Will this header work with my current exhaust system?
This header bolts directly to factory mounting locations and integrates with your stock exhaust piping. Confirm your existing exhaust configuration before installation to ensure full clearance.
Do I need to tune the engine after installing this header?
Headers improve airflow, but tuning is not required for bolt-on installation. Some builders dyno-test after installation to verify peak gains. Check with your tuner if you're running any additional modifications.
What preparation is needed before bolting this on?
Clean the mounting surfaces and inspect gasket sealing areas for oil residue or debris. Remove your factory header carefully—bolts can seize over time. Use new gaskets between the header and intake manifold for a proper seal.
