Its 400 CPSI substrate sits in a 4\" outside-diameter body, with an application rating of 375 hp per converter or 750 hp per pair. Match that capacity and footprint to the engine and exhaust you are building.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSKU:\u003c\/strong\u003e GE-90147\u003c\/p\u003e\u003ch2\u003eClear dimensions for the fabricator\u003c\/h2\u003e\u003cp\u003eBoth ends have a 3\" inside diameter.

They do not promise an increase in engine output.
