This Borla Turbo XL transverse-flow muffler runs a single 2.5in offset inlet to dual 2.5in offset outlets on a 19in x 10.25in x 5.5in oval body. The transverse layout - originally engineered for GM F-Body Camaros and Firebirds mounted behind the rear axle - places the inlet and one outlet on one end with the second outlet on the opposite end, making it well suited to custom builds. Un-notched necks for weld-in installation; T-304 stainless with CFF packing and a reversible design.
