$230 for Cat + $180 for Shorty Header = $410. SVT header, Cat & Flex are selling for about $350 in the for sale section. left over money would cover shipping costs and the SVT dip stick and other minor things you might find.
if i was to buy an SVT header for a ZX3 zetec, is it direct bolt on installation and is there anything else required when installing an SVT header? im fine with leaving the stock headers if i only get 2HP increase not worth the money on a short header. all i know is i need a new cat and the one im planning on getting is the magnaflow for around $300 with shipping and is direct bolt on installation.
