Question how much would it cost?

So how much you think it would cost to delete the cat and resonator just like a ball park price and would it void the warranty??

$100 or so.

please keep in mind, for street use this is considered illegal and fines around 20k will follow... to shop and owner.

look for an exhaust diverter valve basically you can run straight exhaust or stock by flipping a switch...though im sure this is illegal too.

depends if you are talking 2nd cats or primary. if you want a 2nd cat delete and a res delete (Like I have)I would highly recommend it. 100% legal, and doesnt cost much at all.

just do it and be happy. Thats all I can tell you.

However, if you are thinking primary cats, I would advise against it. State depending, but most inspections make it illegal to delete your primary cats.

Potty Pants, stfu.

OP, its all in who you have do the work. I've been quoted anywhere from $50-$300. Deleting your primaries will not allow you to pass emissions if your state or county requires them. Personally, I would get Gavin's headers and keep the stock ones handy for when you need to do the sniffer test.
