The Borla Touring Cat‑Back exhaust for 1988–1990 Jeep Wrangler YJ 4.2L 4WD delivers a mellow Touring tone with minimal in-cabin drone. Constructed from T‑304 stainless steel with ultra-smooth mandrel bends, the system uses a 2.25" inlet and polished 2.75" x 2.5" rectangular tip for a refined appearance. It increases exhaust flow for improved throttle response and efficiency.
