This design reduces potential leak points and simplifies replacement on compatible Lexus and Toyota vehicles. The converter body is made from stainless steel, offering resistance to rust and heat, which is critical for maintaining exhaust system integrity over time. The irregular inlet port shape ensures a precise fit with the engine exhaust ports, while the three outlet mounting holes provide stable attachment to the rest of the exhaust system. The package includes the exhaust manifold, one input gasket, and one output flange, ensuring a complete installation setup.\u003c\/p\u003e\u003ch2\u003eCompatible Vehicles and Applications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eDesigned specifically for Lexus GS300 models\u003c\/li\u003e\n\u003cli\u003eCompatible with Toyota IS300 vehicles\u003c\/li\u003e\n\u003cli\u003eFits Toyota SC300 models\u003c\/li\u003e\n\u003cli\u003eSuitable for Toyota Supra applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eCommon Issues Addressed by This Part\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eExhaust leaks caused by cracked or damaged manifolds\u003c\/li\u003e\n\u003cli\u003eFailed catalytic converter leading to emissions test failure\u003c\/li\u003e\n\u003cli\u003eReduced engine performance due to exhaust restrictions\u003c\/li\u003e\n\u003cli\u003eCorrosion and rust damage in the exhaust manifold area\u003c\/li\u003e\n\u003cli\u003eCheck engine light triggered by oxygen sensor or converter faults\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eWhen installing the Dorman 674-642 catalytic converter with integrated exhaust manifold, ensure all gaskets are properly seated to prevent exhaust leaks. The included inlet gasket and output flange should be inspected for damage before installation. Tighten mounting bolts evenly to avoid warping the manifold. Due to the irregular inlet port shape, verify alignment carefully to ensure a proper seal. It is recommended to inspect surrounding exhaust components for wear or damage during replacement.\u003c\/p\u003e\u003ch2\u003eQuality Assurance and Warranty\u003c\/h2\u003e\u003cp\u003eDorman parts are manufactured to meet or exceed OEM standards for fit and function.
