Expert Reply:

The MagnaFlow Stainless Steel Catalytic Converter, # MF38134, does require welding for installation. All universal fit converters will require welding for installation.

If you can tell me the size of the engine in your 2004 GMC Canyon, if it is a 2WD or a 4WD and if it is registered in California or not, then I can see if there is a direct fit converter that does not require welding for you.
