I have a 2003 GMC ECSB Z71. I am looking for a stock Y-pipe to hollow out the cats on or just cut them off. Are the Y-pipes the same on all of the V8 trucks 99 and up? If not what years would work for me? If you happen to have an extra would you sell it?

 

Don't all shout at once.

 

I would imagine that they are all the same, but I couldn't promise you. If I get a chance to look at a newer model I will see if they are the same. If my order for my y pipe and headers went through then I will have one for sell sometime soon off of my 2000.

 

No they have a few different styles because the trans. cross member is diff.

 

Maybe this will help. The new ones are damn expensive though.
