Well I got a qtp cutcutout but I need to know where the best place to weld it. I have csp lts. Was thinking right after the y but idk if that the best location. Or should it go right before the muffler. Post pics if you have any.
about 10 inches after the y would be the best proformance wise, i know on the racecars they recommend 10 in after the collector before the muffler.
I'd do after the flange so you don't have to cut up a brand new y.
I'd do it after the flange as well. let me know how you like that qtp.
