i had mine routed down thru the fender instead of the normal. synapse bov flange and i also got new 4 ply couplers, one being a transition coupler for going onto the intercooler and all new t bolts. it was 351 shipped. without the couplers and clamps i imagine it would have been about 250. the piping is aluminum with bead rolled edges and i had 2 vacuum ports put in.
