This product is a downpipe-back exhaust system for compatible 2001–2007 Duramax applications.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat does downpipe-back exhaust mean?\u003c\/strong\u003e\u003cbr\u003eA downpipe-back exhaust replaces the exhaust components after the factory turbo downpipe. It does not replace the downpipe itself.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this system replace the factory turbo downpipe?\u003c\/strong\u003e\u003cbr\u003eNo. A downpipe-back system begins downstream of the factory downpipe. It should not be confused with a turbo-back exhaust system.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the difference between the 4-inch and 5-inch systems?\u003c\/strong\u003e\u003cbr\u003eThe main difference is pipe diameter. The 5-inch system has a larger exhaust path and generally produces a deeper tone. The 4-inch system offers a more moderate pipe size and exhaust sound.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhich options include a muffler?\u003c\/strong\u003e\u003cbr\u003eThe 4\" Downpipe-Back w\/Muffler and 5\" Downpipe-Back w\/Muffler options include a muffler. Options without “w\/Muffler” use a non-muffler configuration.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWill the non-muffler version be louder?\u003c\/strong\u003e\u003cbr\u003eYes. A non-muffler exhaust configuration generally produces a louder and more aggressive exhaust note than the corresponding muffler-equipped version.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWill cutting be required?\u003c\/strong\u003e\u003cbr\u003eSome shorter wheelbase, cab, or bed configurations may require trimming an intermediate pipe.
