Magnaflow uses a straight through perforated core for low back pressure that improves the horsepower output of your engine. By using 16-gauge stainless steel for the body, end caps, and core you get long life for your money. By densely packing in the stainless steel mesh and high density high temperature resistant acoustical suppression material you get that signature Magnaflow rumble that is built to last.
