I bought a set but they dont bolt up to the Ypipe. /forums/images/graemlins/angryfire.gif My stock Y pipe bolt circle 2.5" and the edlbrock are 2.25" So now I need to decide to send them back to get my money and keep the stock exhaust, buy the TES system and hope it "bolts in" or get full lenth headers and build a new dual system. /forums/images/graemlins/dunno.gif /forums/images/graemlins/burb.gif
