So earlier this year I felt something wasn't quiet right with my car and I traced it down to my Berks HFCs which I installed on the 13/05/2009.

Ok so yesterday I got around to getting the old ones replaced after reading that after-market HFCs tend to last around 2~3 years (this bit of info really surprised me )

well let me just say I was right about my suspicions, both cats we're nackered. Both had the metal resonators were dislodged and one was pretty badly burnt as well.

I went for the Invidia HFCs and so far so good. Noticed the power I lost immediately and so far no CEL





and a very short clip on the drive back home:




That Genesis to my left has a big turbo

 

I didn't know that either.. Nice GTR and also isn't there an option to have the genesis coupe turbo from the factory?

 

damn ! i have the same ones which mean they probably look like the pic fml

 

More reasons to go with the ART pipes instead of HFC's.

 

^ Yeah I agree I would have gone for Test pipes.....But I bought the Invidia ones in a hurry anyway still happy with the purchase.

Yes you are correct, I should have said it's got a MUCH bigger turbo installed lol

 

How do you feel about the Invidia compared to the BERK?

- Sound?
- Performance?
- Quality/fitment?

 

Woah! My HFC are as old as yours and don't even look like that

 

what exactly did u feel ?
my FI HFC are also 2 years old and they seem Okay so far.
but still gotta ask u this . . when these go bad, what are the things i expect to notice and feel with the car ?

anyways. . when my HFC gets exhausted i wud get GTM test pipes for sure.
but wud they fit with my FI catback ? or shud i get em from FI only ?

 

i just got the berk hfcs, hope they last longer than 2 yrs

 

To be completely honest I can't comment on that right now as the Cats are still breaking in. They sound slightly louder right now because they're still in the break-in process.

As for performance, I quickly felt the power I lost. Now is it more than the Berks? I can't really say TBH, I installed the Berks over 2 years ago on my stock exhaust and when I did it back then I defentaly felt and improvement. These CATs do seem to pull slightly harder after 4k but that could be just all i my head.

As for quality/Fitment, there were no problems, Quality is top notch and fitment is great as well (I never installed mine, I got them installed by a shop) The only difference is that these CATs don't attach onto the side bracket like the berks so I was able to take out my bracket which were connected to the Berks.

Well at some point (~3 months back) I remember my car back fired 2 or 3 times in 1 week (my car is tunned by technosquare) I found it weird back firing but didn't think much of it. A few weeks later I arrived home and had the car idling in my drive way and I could hear the metal inserts on the cats rattling, not very loud but the only place I could track it down to were the cats.

Finally it was the power that I felt I lost, I would get serious hesitation at times trying to accelerate from a stand still (I'm going to be cleaning my MAF and Throttle bodies soon) but I'm sure the Cats played a part in that hesitation.

Hope this helps. TBH I didn't expect them no where near as bad as they were, so I'm happy I got them replaced.

As for installing the GTM Test pipes you shouldn't have a problem, they should fit any exhaust system as far as I'm aware, someone correct me if I'm wrong.

You'll love the Berks, I loved mine the moment I got them installed and they have done their job as far as I'm concerned, just get them checked after 2 years of abuse

 

so that video is of you with the HFC invidia's on stock exhaust ??
sounds awesome if so

 

have a look at his signature

 

No nothing stock about the exhaust, it's the Invidia HFCs with the Invidia Cat-Back system, as well Stillen Gen 3 filters.

 

haha i dont believe in vehicular abuse :P

 

wow. those HFC's are completely toasted. Have you contacted BERK? Maybe they can replace them or something. I don't believe that HFC's are only supposed to last 2-3 years. Maybe with boost and higher EGT's but this is ridiculous.
