Welcome to the site.
First, check your welds and make sure they are not cracked and do not leak fresh air into the exhaust.
Second, go to the DIY/How To section and find the thread on how to use non foulers to trick to O2s
Third, before attempting anything else, ask us first.
We can help you save so you can spend it elsewhere
