Gutted Metal Cat Any Issues?

[boostn0199]

I want to gut my xforce metal cat but I know when doing this to stock cats unless you have a straight pipe in it you will have turbalance issues with the flow but since the metal cats are basically designed in a straight pipe design will this still apply to gutting a metal cat? Pic attached.

Street or track car? Its not worth the risk on a street car imo, maybe gain 5kw max from a de cat.

Maybe just do a replacement pipe you can bolt in and out, save you destroying a perfectly good cat.

Looks pretty similar to the jjr decat pipe to me. Wouldnt think there is any issue.

I would straight pipe it.

And why break a good CAT anyway? either keep it for later...

or

get a straight pipe made and bolt it in.

sell metal cat.

money spare for beer.

Its a track car. And yeah the metal cat melted so its useless so just thought might aswell make use of it.

If the metal cat is stuffed, then yes bash it out.

For optimum flow, yes a straight pipe is best, but a gutted cat will still flow better than a collapsed one

Will it be worth getting the tune checked after running the gutted cat.

I wouldnt think so mate. Pretty minimal gains.

[R31Nismoid]

id get it checked, always safe to have things looked at.

Thank God I didn't get the xforce, heard so much about them collapsing under heat.

[boostn0199]

Ye POS 400 bux waste. Would of just decat straight away if car wasnt street driven back then.

Totally, took mine on a skid pad a few times and the thing fell apart, not to mention the massive restrictions. Took it out and it was already crumbling so I bashed internals out. Job done

You'll find its not just xforce.

When you are running 300rwkw, drifting... with the heat being sent down its little surprise they melt as its not what they are designed for.

hope this isnt a dumb question but could you run the cat further back in the car where the difference in temp may mean it wont melt?

[R31Nismoid]

Nope. It's emissions requirement from a legal point of view, given if you run a cat to start you are trying to follow the law

You'll find the temperature won't change that much further down the pipe, at idle etc and cruise maybe, but on full song the EGTs would be nearly the same as the OEM position
