Built from T304 stainless steel with a 17-gauge (1.4 mm) wall, the tube is polished for added corrosion resistance and a finished appearance. It's intended for non-complex straight runs in 4\" systems and should be installed or fitted with professional guidance when doing more than a basic swap.\u003c\/p\u003e\n\n\u003ch3\u003eWill this pipe fit my existing 4\" exhaust system?\u003c\/h3\u003e\n\u003cp\u003eThe pipe is manufactured with a 4\" inlet and outlet and a true 4\" internal diameter, making it compatible with most 4\" exhaust components.
