From catted x pipe to off road x pipe

[saleenssc1989]

I currently have a catted x pipe on my 2003.
I think I want to convert, to a off road x pipe instead, will I need to have my car retuned for this change?
What brand do you guys recommend, any advice would help narrow down what im going to purchase.

Nope you're fine, you'll just need mil eliminators.

Get the bassani catted x. That way when/if you ever need cats again you can swap them in under an hour. I have had the modular 5 piece on my 01 and now my 03 very happy with its fit and sound.
