Air tube on aftermarket H pipes??

I seem to recall the air tube pipe being a clamped slip fit..............

I know on 94-95,its a slip fit with a clamp.
But it was always a pain in the ass to disconnect.

I now use the heater hose method.

Tip for removing a stuck air tube:
Lots of WD40 or PB Blaster to soak the joint. The get a suitable drill motor, 1/8" drill bit and a 1/8" Allen wrench. Drill a 1/8" hole all the way through the air pipe about 2" from the joint. Stick the Allen wrench through the hole, and use a pair of ViseGrips or large open end wrench backed up against the Allen wrench. Hammer away on the ViseGrips or the wrench, and the air pipe will come off. Use the Allen wrench and Visegrips or large open end wrench to help hammer it back on. Use a pair of stainless steel sheet metal screws to fill the holes.

Yes it does work, and I have done it. However, it helps if you are skinny or have the car up on a lift. There isn’t much room to swing the hammer when the car is on jackstands.
