[QUOTE="Gilaguy23, post: 430108, member: 19498"] My $.02 worth. Generally speaking vehicles that run a 02 sensor after the cat are affected in a bad way when the cat(s) are removed. Thats not you though. Ive had 3 vehicles that the cat we'll say fell off.....errrr no, it was stolen....yeah,yeah thats it :0 . I did not like the results on them as it made 0 increase in power or mileage. Plus on a jeep or like vehicle it will worsen fumes and will gag you when you run topless or with the back window rolled up if its a softop. Adding a 90 to make a side dump exhaust helps but all in all its not worth it IMO. BTW, regardless of smog laws in your state keep in mind it is illegal to remove any federally mandated smog equipment like cats unless its now used on closed course events so they say. Just sayin.
