HKS Silent Hi-Power Cat-Back Exhaust - Toyota Altezza (SXE10) 1998-2005

HKS builds the Silent Hi-Power cat-back system entirely from SUS304 stainless steel and pairs a redesigned internal silencer with Advantex glass wool packing, holding proximity noise on the Altezza to 92 dB, the same reading as the factory exhaust. The system runs a 60mm center pipe into an oval TYPE-S main silencer and exits through a single 120mm tail. It weighs 9.5kg, carries JASMA certification 03S00876, and keeps roughly 145mm of minimum road clearance on stock suspension. The tail is shaped to sit with the factory rear under spoiler in place.
