judiciousjoe Posted May 31, 2014 Share Posted May 31, 2014 I had Cobra HFC's fitted to my Nismo cat-back by Abbey Motorsport at the beginning of May. I must say what a difference! Apparently the Berks are having issues with emissions on MOT's and the Cobra's are British built. The sound is incredible, hardly any noticeable difference upon idling and just cruising but put your foot down and it snarls, growls, pops and bangs beautifully. I will get a video up for you soon. It is definitely a worthwhile mod and you are in very safe hands at Abbey. 1 Quote Link to comment Share on other sites More sharing options...

kinglozzer Posted May 31, 2014 Share Posted May 31, 2014 Just got a Cobra fitted and am now looking at HFCs so I'm eagerly awaiting this video too! Quote Link to comment Share on other sites More sharing options...
KyleR Posted May 31, 2014 Share Posted May 31, 2014 Not heard any issues regarding the Berks at MOT, except from people that haven't got them up to temperature before the test, the same will go for your Cobra's. Quote Link to comment Share on other sites More sharing options...
judiciousjoe Posted June 4, 2014 Author Share Posted June 4, 2014 I will get a video uploaded for you guys this weekend. I was waiting for somebody to be able to record it with a camera from behind. It will give you a general idea of the sound, but obviously hearing it in real life is best. So if any of you live near I am happy to give you a demo/test drive.

When I booked my Z in with Abbey I requested to have Berks fitted. However, Scott advised me that they recently had issues with customers Berks burning out and essentially becoming test pipes. So they now use a company called Cobra. They were custom made on Abbey's behalf and sound very beautiful from 2k revs onwards! They would still fit Berks to a car if desired, but don't advise it and now prefer the quality of Cobra HFC's. Quote Link to comment Share on other sites More sharing options...
KyleR Posted June 7, 2014 Share Posted June 7, 2014 If something like this has happened, then why is this the first the forum is hearing about it? I'd like to hear from these customers or Abbey Aren't the Cobra's near £600 or something? Quote Link to comment Share on other sites More sharing options...
mouthwash Posted June 7, 2014 Share Posted June 7, 2014 Aren't the Cobra's near £600 or something? Yep, I was going to get some until I saw that price. Quote Link to comment Share on other sites More sharing options...

judiciousjoe Posted June 7, 2014 Author Share Posted June 7, 2014 I'm sure Scott or Mark at Abbey would be more than happy to answer any questions in detail. Their knowledge of cars is 1,000,000 times more extensive than mine! I didn't want to start a forum war about HFC's! Quote Link to comment Share on other sites More sharing options...

It's just that Berks are very popular on here and regarded as one of if not the best HFC's and it's a bit of a shock to hear about the issues… Quote Link to comment Share on other sites More sharing options...

judiciousjoe Posted June 7, 2014 Author Share Posted June 7, 2014 As promised, here is a quick video of the Nismo cat-back with Cobra HFC's. Let me know your thoughts, good or bad. Quote Link to comment Share on other sites More sharing options...
Mark@Abbey m/s Posted June 11, 2014 Share Posted June 11, 2014 (edited) We have had issues with getting Berks passed the MOT even if they are warmed up aggressivly. We went over to a Cobra HFC ( they aren't custom made for us) which uses a better quality Catalytic brick (euro 5 spec) works far better than the Berks we have used before. We can supply the Cobra HFCS for both types of cars DE/REV UP and the HR/VHR for £540-00 inc vat.

glrnet Posted June 12, 2014 Share Posted June 12, 2014 Some of you will remember the car developed a peculiar droning noise develop on the way back up through France last year, I was running Berks HFC's and Miltek on a NA set up (I mention this as it is relevant and will explain later). Anyway the droning noise turned out to be a failed HFC (which, in fairness Berks replaced FOC under warranty) The droning was caused by the substrate in one of the HFC's becoming detached from its internal fixings and vibrating around in the casing. Here's a short clip of the offending item ( the HFC, not me!! ) You'll need the volume on to hear it rattling around. It's fair to point out that the other HFC was absolutely fine. https://www.youtube.com/watch?v=eWqJL-aOpQw I have since replaced the Miltek with an ARK system and reverted back to standard cats for no other reason than noise levels (yes I'm an old fart Neilly P ) Now, the reason I mentioned NA is that I am aware of someone else who was running FI with Berks HFC's and they both pretty much had the stuffing literally blown out of them. Both these events occurred last year and hopefully were isolated incidents. 1 Quote Link to comment Share on other sites More sharing options...

CJRamze Posted June 12, 2014 Share Posted June 12, 2014 Ordered from Clark Motorsport and they always throw in cobra leaflets. I wasn't aware they were British. Makes me want to move to them and with Berks possibly failing I might aswell either decat or cobra hfc.

Dynamic Turtle Posted June 14, 2014 Share Posted June 14, 2014 Bit worried to hear this - had the Berk+Milltek treatment at Abbey last year (about 13k miles ago). What kind of warranty do Berk offer against this kind of issue and is it possible they might also damage the backbox? Quote Link to comment Share on other sites More sharing options...
WINKJ Posted June 26, 2014 Share Posted June 26, 2014 any more news on the Berks failing MOTs? Quote Link to comment Share on other sites More sharing options...
