I am not planning on using a y pipe. I am hopefully going to connect the duals straight to the headers. Maybe using flexpipes like you said.
I understand the reasoning for flexpipes but why do we need them now and never used them before. I don't remember puting flexpipes on the mustang, t-bird, or fairlane. I thought it just bolted straight onto the header.
Warmonger, I heard you were selling your headers. Is this true. How much and why?
