Gutting My Cat

[asromanut]

Ive got the following modifications to my BF 6speed Auto

custon edit and tune from nizpro

valve springs

drilled injectors

so far my power is up around the 270rwkw mark.. my question is if I gut the cat how much of an increase in power and torque should I expect?

I know some of u dont agree with what I might be doing but I just want your opinions that's all.. im going to get it retuned after I gut it

Gut it or pipe it? theres a difference

You should get around 30 rwkws. that's what I have seen .

Makes the car sound much nicer too.

gutting it, keeping the stock ford cat but removing the insides

[Fat-Tony]

if you are removing the insides of the cat and leaving it, it will cause a bottle neck in your exhaust and sound tinny to. Putting a pipe through the cat is the way to go.

How do you gut the cat when its only flanged on one side? Do you have to cut it off and then reweld it or can you get the welded side flanged and then take it off and put it on whenever you want?

How do you put a pipe through the cat? What is the size that can fit in there?

Hey fat your right about the tinny sound when it's idling, but man, under WOT conditions..

And Nesh, yes it's a full cut and shut jobby.

So can any exhaust place do it for you? Also how much? Who did yours ENVY?

doing this is illegal, so finding a exhaust shop to do it might be a bit of a hassle
