Elliptical welded center/center muffler, 2.25-inch or 2.50-inch free flow straight through center muffler, wrapped in stainless steel mesh. 6 inches x 8 inches x 14 inches, mainly affected by the central drum. But in the modification industry, the focus is generally on high-speed performance, and modified parts will reduce the original factory's back pressure appropriately, so the drum is usually shorter and thicker than the original parts. Street running and racing don't even have drums installed.
