Get your local exhaust shop to remove and if they wont empty the insides out and refit it for $100 go somewhere else. Another way is go to the wreckers and take it home and do it yourself. Take your DIY hi flow cat to the exhaust shop and they should swap them over for $50. Most cats would be stuffed in 12mths if your running around 300rwkw. So long as it looks standard from outside you wont get into trouble with the law. Link to comment Share on other sites More sharing options...

The substrate also becomes inactive over time. If you get done all you get is a fail reading and you go buy a newie and fit it. No great drama Link to comment Share on other sites More sharing options...

Slightly dearer than metal cat because it has much more (5" dia v's 4") substrate. Link to comment Share on other sites More sharing options...

I've heard the Punched CAT is the easiest. (meaning a pipe punched through the CAT and welded in).Also how is the exhaust designed. Meaning how does it fit together and get removed.Can you unbolt a section and work on it then reinstall? If so what part?Hope that makes sense.

The xforce one is just as good flowing apparently (metalic) and about $300 on ebay. www.catco.com.au has some comparisons. I think the benefit of these 2 cats is that they provide close to 0 restriction on a 3" pipe where the metal cat is about 10%. When it comes to performance sometimes it's worth paying a little extra Edited 21/08/07 05:47 AM by tquarrell Link to comment Share on other sites More sharing options...

I have seen half dozen cut open and all use the same insides. Obviously the more surface area the better the flow. Link to comment Share on other sites More sharing options...
