    Cat(s) Delete

    Hi all, I currently have a Flowmaster Super 10 rear axle dump with a massive 4"x15" tip. I looked under my truck the other day and saw 2 cats, I'm wanting to delete those, but how do I go about? It's such a tight space! How will deleting these effect torque? I know how it will effect horsepower, but I need to know about back pressure, and if I do a delete what do I do with the O2 sensors? Will I need a tune? Thanks
    Btw 4.6L V8 3V

    Do u race? Do you run water instead of coolant? Full slicks?? No? Lol. Me either. Do yourself a fav. Call 5star and get a programmer and get your truck tuned. They can make it the way u want it. Your just gonna have problems by hollowing out your cats. Or cutting them out. If your looking to get louder. Start looking at long tube headers. I'd leave your cats. But that's me. ^ it is also illegal. Just sayin. Good luck

    Last night I went on ahead and bought a tuner, i dont know about the long tube headers, I think it's pretty loud since I set off a few car alarms yesterday with my exhaust! 😳
    Maybe in the future...

    There cool if u don't like customs tunes. It works a lot better if they tune it specifically to your vehicle. But anyways. Good luck with it

    Wow, how sad that after all the questions you have asked here, and all the info you have been given here, that you would buy a crappy ass flashpaq and think you could use it with longtube headers.
    Black Chrome is bagged, blown and a pleasure to own.
