so debating about getting some hfcs...but heard that they do eventually get clogged or wear off real soon. so they dont last for long term use.

anyone experience this???

 

Just by the nature of how they are made they will not last anywhere near as long as OEM (which should last life of car)...

You should expect 20-25K miles from hfc (could be more, shouldn't be much less)... if you are looking for longer leasting, stick with OEM or consider test pipes (but the negatives with tp outweigh the short life of hfc IMO)

 

Consider the material, too. Fast Intentions 300 cell cats are metallic. Many other HFCs are ceramic.

 

Life of the HFC really depends on the quality of the cats and also how much beating they take. Some aftermarket ones last well over 30K, when some will blow out after 15K or so. BERK & FI seem to be the best options out there so far.

 

So it seems like it last a little longer than I thought. I was thinkin maybe 5k-10k.

this is good to know, good info. Thanks guys

 

Get the ART pipes. You won't regret it.

 

^ totally awesome, unless your exhaust leaks, then your car will sound bad because your exhaust sucks


that's what happened to me at least lol

 

my labrees been on my car 2-3yrs, still like day one.

I had fast intentions cats and they burned up after about 4k miles. I've been running tp's for about 20k miles now

 

what was the indication that they went bad?

 

He must've been running too rich... The FastIntentions metal cats are quality - held up just fine for over a year NA and also for a couple months I had cats on my turbo setup.

why do you keep doing that?
