I had the rears deleted and it runs fine. Had to gut my cats because my setup just kept blowing them out >

t-rocks firehawk

on my 02 ta i gutted my cats and used o2 sims 30k miles and never a problem. now there illegal getting hard to find and expensive at least in my neck of the woods. i have more bad from others as far as reliability. my firehawk i had the cats deleted because i had one go bad and there $86 a piece. i found a guy to delete them for $20 in a about 15 min.now i have a little bit of a raspy sound when i get on it but only when my foot is on the floor. its a little louder when idleling but not much so in my opinion its worth it if u cant afford headers like me.hope this helps
