Are those LT or shorty's?

@NICK13520 These are the OBX long tube headers for a 2002 Silverado

is that 2 or 4 wheel drive? thinking about getting a set for a 4wd but want to make sure they will fit

@redneck9491 Its a Z71 4x4. We did have a front drive shaft clearance issue. But if you test fit the left side first, mark where the drive shaft is. You can heat that part and reshape it with a hammer. We had to do it after we installed it and it was a pain. Remember that engine "torques" in its mounts at high loads so you need to give a little extra clearance to allow for that too.

I ended up installing a lift a year or so later and that would eliminate any drive shaft issues.

is it just me or does it say 5.3 in your title and 6.0 in your description so did you swap in a 6.0 or leave your 5.3?

@05silvy Really late reply but its a 5.3 engine with the "y-pipe" from a 6.0 The 5.3 y-pipe merged into one pipe. The 6.0 "y-pipe" remains duals so I could have true duals out the back.

@05silvy its a 5.3, the Z71 package wasn't offered on the 5.3 motors for that year of truck
