hey guys
just got a new hi-flow cat installed and just wondering if they have to be run in or not?
heard from one place that they do for the first 250k's so that the honeycomb can dry out or something to stop the cat blocking up
now the place that i've just had the cat installed said that this was the firsted his heard about running in a cat
just wanna know who is right?
cheers rob

I've never heard of it either.

Never heard of it either!
Maybe it was the case when they were first introduced.

i got a new cat installed a week ago

and exhausttt


theres this cool whistle airy sort of sound i can here now
not sure why
but its sweeet

Name names...who said the cat had to be run in? :)

The honecomb is a ceramic, coated with a platnium (or similar) catalyst.

The only thing that could possibly dry out is the ceramic...which by nature should have no water in it being baked at a high temperature....even then, not much will will dry out when coated with a metal...

Though I could be wrong *shrug*

haha no names lol
but it was from a known name company,
who knows it might have been there in house cats or incase the cat does calapse it cant be claimed under warranty or something

haven't really noticed any difference when changing cats
but it seems to ride abit smoother

Maybe they meant real cats.

The general rule of thumb is:

If it doesnt move, it doesnt need to be run in.
