Ok Im going to dispell some BS that has been going around here and other forums on the VG30 headers not fitting vg33 blocks on a D22 frontier. I have a 2002 frontier 4wd crew cab long bed! I also have a 3 inch body lift installed. The Headers DO FIT, once again The headers FIT with some modification. You need to drill out the mounting holes, drill and weld new bungs, slightly bang in the exhaust on two sides. and weld a custom 1 foot piece back to the y pipe. I believe it will fit without the body lift but im not 100% sure. It is a very tedious process but I have done it. once again i repeat I CURRENTLY HAVE VG 3.0 LONGTUBES ON MY TRUCK, so DONT TELL ME THEY DONT FIT! I was sick and tired of people always arguing about certain parts and fitment so I bought them, took the risk and it payed off! I hope this clears every thing up. Ill upload pics in a couple min.
