Default Exhaust question

Hi all

Cars back in for retest today I have run some Cat-a-clean through it as it failed on emissions previously.

Its also getting an oil change but my questions are as follows:

1: If it does fail emissions again is there anyway to tell if its the 1st or 2nd cat causing the issue?

2: Can I remove the second cat and replace with the straight through pipe I have set aside leaving the first cat in place?

3: How much am I looking at to replace the catted downpipe that will lead to the straight through pipe? Im struggling to find a replacement part or price via google

4: Can anybody tell me who/where would stock a catted downpipe?

Thanks in advance

Dave

What car is it?
Is it currently running a standard cat?
