Taking off cats gonna effect Tune?

[Laxpaint5]

I had my car tuned with bassani X pipe with high flow cats. I was considering taking them off but I was not sure if that would effect my tune? Any experiences?



Thanks Guys

It shouldnt make a big enough difference to require a change in the tune.

amazon told me that it could but I have a conservative safe tune so I am considering taking them off
