Now I really know your a troll. Unless the cats were absolutely knackered you wouldn't gain that much.

[kuzman89]

except it's a $10,000 fine if caught, it's poisonous to other road users and for the cost of a few 100CPSI cats it really ain't worth it.

[COL3SY]

Full of shit lol I have the dyno sheets and pics of the cats to prove it! They were pretty bad!!

Price of new high flow cats: Few hundred
Price of fine running gutted cats: Few thousand.

Above answers stand: No point.

Are you cats stuffed?

Yes - Replace them
No - Leave them alone

1. Can I ask what you mates car is to have 350rwkw?
2. Depending on the dyno and operator, a difference of 30rwkw can be achieved. So dyno print outs prove nothing.

Before and afters at the strip would prove something though.

Your car and your mates car only makes 224rwkw stock. So if he said hes getting 320rwkw he must have some work done to it and thats massive $$$..

I cant see anyone spending all that money doing work to a car to gain and extra 100+ rwkw and then bashing out his cat with a broom stick and then it miraculously gaining and extra 30rwkw...lol

Only when the cats are breaking up anyway.

A perfectly fine and functioning cat won't affect the output very much at all.

In your first post you asked if anyone's done it. Now you say your mates done it and gained 10% power increase? Doesn't make much sense champ.
Id have to agree with what others have said. From what I understand it would sound crap, no power gain (or even losing power), and highly illegal. Not ideal for a road car

[COL3SY]

Coz his done it on a bf xr6 turbo not a Holden

Any chance that you and your mate happen to use the same garage for dyno runs?

I'm seeing some happy dyno figures floating around in this thread.

Either way, if you already ahve 100cpsi cats to you will acheive nothing gutting them.

[COL3SY]

Lol look at my show my ride! And the dyno sheet!! C a autofashion have done my work

As previously stated... dyno sheets are not the most reliable measure. For example, put the same car on a mainline and a dynamics dyno you can expect a 10rwkw difference. The dynamics being teh happier of the two.

Just saying.

Anyway, off topic.

Gut cats = bad and silly in your case as you already have high flow.

All I wanted was a simple answer but it seems to hard for ppl on this forum

We did it in a VY HSV just before a cat change to see the change in power between the two (stock and gutted).. Gutted cats lost 4RWKW

Errr...?

No point...

That should have been the end of the thread then. But after you got your simple answer you continued with:

So were you after a simple answer or were you after a simple "yes"?

[COL3SY]

He didn't say he had done it, unlike the other person said he has done
