Hey everyone, will I need to be retuned if I remove my cats? The car has an ARH longtube system but id like to remove the cats for a little bit more flow and loudness. Magnaflow mufflers will still keep a good tone and not stupid loud. But I do not have any down stream sensors. I have my up stream and afr sensor and that’s it. So technically it shouldn’t need a retune correct? Feel free to correct me if I am wrong. Thanks!
