thanks for the quick response! i'm going to have the OBX LTs -> high flow cats -> manual cutouts ->x-pipe -> dual mufflers and out...still young and dumb i can take loud for now! i plan on a tune and e-fans later but could do them right now if i had to. good to hear you're not setting off any CELs though!

Hi hockeyfanjeff
the cats i used came off a 5.9 liter jeep, the buns face forward so I had no problems with oxgen sensers for the front,did not need any longer wires either, used the back buns
that came with obx y-pipe, I have the magnaflow muffler and it is loud and deep. no cel with this setup. I can tell you i picked up three tenths and four mph at the track with headers! I like them!
