    You can use a Y pipe with the lt headers. I used the TSP Y and added cutouts on each side.

    when you get order the headers it should have a link to what y pipe you will need. the stock replacements wont fit.

    no problem. the replacement ory will probly work with shorty headers but who wants to waste money on those.

    I deleted the cats & used the rear o2 simulators. The cutouts are cut into the Y pipe about 10" after the collectors. After I got the Y set where I wanted it, I welded all the connections and got rid of all the exhaust clamps.
