So it was time for me to replace my cats and O2's. Codes are now gone. flowmaster system went in without any issue. Now I'm trying to mate my existing muffler to the 3rd cat flange/donut and can not seem to find any solutions. Every shop I take it to all want to do the same thing, cut off the flange which I'm trying to avoid. Been trying to find a adapter such as this. https://www.amazon.com/gp/product/B0015KZL26/?tag=wranglerorg-20. No luck so far. Any ideas? Thank you in advance. Here is the flowmaster and muffler.
