hi guys,

If i hollowed my existing cat out on my ef xr instead of getting a high flow one and spending $300 would it do the same thing.
what are your opinions on this even if it is illegal.

it would do the same thing with the added bonus of causing cancer :)

I doubt you will notice any difference from a good condition standard cat, to a hollow cat. Not worth making yourself sick for IMO.

Hollowing out your cat comes with some hefty EPA fines - i've heard in the order of thousands of dollars.....

You can actually loose power by gutting the internals of a cat....

yeah the fine is huge, bad idea, its better to get your standard cat and chop the ends off so it has 2.5" openings at each end, standard cats modified in this way are the best way to go, 'high flow' cats in general are a waste of time and money.

im positive its $40,000 << yup not a misprint and jail time!!!

the main reason is a gutted cat wont convert the carconagenic Benzine into carbon monoxide and water
