I have been told my cats are on the way out...

I think it might have something to do with them being almost flat (the results of a low car, and my mums driveway)

Any recommendations on some good hi flow cats??

yep, a 3" pipe bolted to your headers, and then bolted to the rest of the system, if your cat gets blocked, it will blow your head gasket, so a 3" pipe is much better, and will give you greater throttle repsonse.

or gut your current one, lots of people do it, and if your done by the EPA, fit an el cheapo for testing, then remove it

If you get caught without a Cat its something like a $10,000 fine, so I wouldnt think the extra 5kw gain or whatever would be worth it.....

Agree.

I used a set of second hand V8 commode cats on mine as they flow well and were cheap ($100 / set) Make sure you shake them, look inside and check for the white dot, and hey presto.

I painted mine silver with High temp paint, and they look new.

Good luck.

Has anyone tried the high flow red backs??

XR8chic · 03-03-2002, 15:41

OK.... I decided to go for the high flow super cats.

more expensive, but they have a bigger opening on them (2.5" instead of the red backs which have 2.25")

has anyone used these before?
