Investment casting allows for an optimized design that smoothly transitions exhaust flow from the massive 6\" body to the dual 2.5\" exhaust legs. The casting also provides a beautiful look that turns the entire downpipe into an attractive gold finish as it wears in from heat cycles over time.\u003c\/span\u003e\u003c\/p\u003e\n\u003cdiv class=\"shg-c  shg-align-left\" id=\"s-c70c44f4-0067-4e36-b96e-749c45fa577e\"\u003e\n\u003cdiv class=\"shogun-heading-component\"\u003e\n\u003ch1\u003ePERFECT FIT\u003c\/h1\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"shg-c\" id=\"s-5ab0b0fb-e6c8-4bb9-9741-020dd9f35749\"\u003e\n\u003cdiv class=\"shg-rich-text shg-theme-text-content\"\u003e\n\u003cp\u003e\u003cspan\u003eThe B9 3.0T hot-v style engine has a unique center-mounted turbo with a large downpipe that quickly splits into twin-sided exhaust sections.
