It joins the compatible factory mid-section or the matching Kooks header and X-pipe setup, so you can choose the rear exhaust first or include it in a fuller build.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSKU:\u003c\/strong\u003e 21606750\u003c\/p\u003e\u003ch2\u003eShotgun character and a darker finish\u003c\/h2\u003e\u003cp\u003eShotgun is the more open, louder-oriented muffler design in the Kooks active-exhaust range.

That is a different setup from keeping the factory front exhaust.
