who only runs one aftermarket header?


Oct 18, 2004
hi, i recently bought a postons passenger side header and crossover. I know that the stock PS header is the restrictive one. Does anyone here run a stock DS manifold and a poston PS header? If so, how does it work out for you? Should i use the crossover or leave the stock one on, ive heard stories of the poston crossover being a pain to seal up???
any info appreciated
Only replace the DS header and stock crossover pipe when the are leaking. There is no performance increase by replacing them with the ones from Poston. The PS side header is a must. Brad
