The HKS Silent Hi-Power Catback Exhaust System brings refined performance and Japanese precision engineering to the 1990–1993 Toyota Celica Turbo All Trac. Built from premium SUS304 stainless steel, this system is engineered for enthusiasts who demand both quiet operation and measurable power gains.
The TYPE-H sport-style round silencer delivers a sleek, factory-quality appearance while improving exhaust flow and engine response. Thanks to HKS’s innovative Silent Chamber technology, this system minimizes cabin drone by reducing low-frequency noise — without diminishing performance. The inclusion of Advantex glass wool ensures exceptional sound insulation and long-term durability, while a redesigned inner silencer structure enhances both aesthetics and flow dynamics.
Fully compliant with emissions standards, the Silent Hi-Power system retains all factory emissions equipment intact. Approved by JASMA (Japan Automotive Sports Muffler Association), it guarantees high build quality and street-legal performance. The result is a subtle, deep tone outside the cabin and a comfortable drive inside it — ideal for drivers seeking an upgrade that enhances both refinement and responsiveness.
