If anyone is interested to know, Hotshot has begun production for its 1990-1993 2.2 5SFE Celica Headers, and is now taking pre-orders.
Similar option is the Genie 4-2-1 header -- guy on Celicatech installed one and says he loves it. Once again, the Cali owners can't take advantage cause neither the Hotshot nor the Genie have room for more than one cat.
Price is $389 for the first 12 people, valid until Feb. 28. After that it's $457...which seems pretty high considering Ripp's Camry 5SFE is $469 with a high-flo cat, and Genie's is $330 without one.
