What kind of modification does it take to adapt the stock Y-pipe to long tube headers? I want to use a Jegs off-road y-pipe that's fit for the stock manifolds and cut that to fit if possible. I see a lot of people running duals with long tubes but I want to merge into a single 3" tailpipe on the passenger side in stock location. Feel free to post some pics if you got longtubes to show how they're routed.
