Does anyone make a direct replacement y-pipe with cats for a 2003 Silverado? Everything I seem to find is for headers and very expensive.

I agree but I don't have tuning software and don't know of anyone in my area that does. Thanks for the offer mitch but I actually found someone on here that is selling the whole y-pipe with the cats. They have 90K miles though but hopefully they will get me to pass emissions at least.
DAMN!!! I just took the stock cats off of my 2000 to the salvage yard to recycle them when i bought the Dynatech system. Guess I had too much other BS sitting in the garage!
