Replaces both rear mufflers with straight-pipe sections capped by dual burnt-blue rolled tips, delivering an aggressive exhaust tone throughout the RPM range. The loud option for owners who want the rear mufflers gone entirely.\u003c\/p\u003e\n\n\u003ch3\u003eWhat It Does\u003c\/h3\u003e\n\u003cp\u003eThis is a muffler delete, not a muffler replacement. Both factory rear mufflers come out and get replaced with straight-pipe sections that exit through dual burnt-blue rolled tips. The result is significantly louder than any muffled axle-back, with an aggressive note across the entire RPM range and no drone management because there are no mufflers to drone in the first place. Best for track-focused builds or owners who want maximum aggression and don't care about volume.\u003c\/p\u003e\n\n\u003ch3\u003eCritical Fitment Notes\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eRWD MODELS ONLY.
