What are peoples recommendations (Tim as well) on the headers set up in terms of catalytic converters.
I am looking at getting a set of headers soon and i am wondering what i should do in terms of the stock cats
a) are they known to fail after a while? (car has 145k on it)
b) if they are known to fail what kind should i get (Brand and CPI, I have heard some positive things about magnaflow 200's)
c) if they are not known to fail should i get them changed anyway? price to performance wise what am i looking at?
d) if i do upgrade how difficult is it to make sure all the sensors are done up correctly upon installation of the new cats?
e) what would the total fabrications approximately add up to ( installing plus work done to get the sensors in the cats etc)
f) who can give me a good name in Melbourne to get the work done because I am super keen!
thanks everyone
