Front pipes: The Touring and Track Edition Exhausts include a full 3 frontpipe that is designed with a unique flange and gasket to ensure the full diameter from inlet to outlet. This frontpipe is integrated into the design of the exhausts. AWE exhausts are not designed to mate with other aftermarket frontpipes. Featuring an integrated front pipe, robust midpipe resonator, thick-walled T304L stainless steel, and a 15 lb weight savings over stock, the Track Edition n is the do-it-all configuration for those who prefer their volume like their speed. In place of the 180 Technology resonator in the rear lies a Track Edition straight section. As a result, this version is known to get rowdy in mid range acceleration/deceleration and cruising, and may be too much for some. Youve been warnedespecially with a downpipe.
