jamess115 Posted October 2, 2014 Share Posted October 2, 2014 Hi everyone, I am the soon to be owner of a Nismo cat-back exhaust and would like some opinions on whether to get HFC's. My goal is to keep the sound relatively OEM with a nice deep tone at low revs.. and I know HFC's will crank up the noise but equally many on here really advocate them. I am interested to know why ? Are there any performance gains to be had with/without HFC's & a Nismo without a remap ? Thanks in advance Quote Link to comment Share on other sites More sharing options...
G1uk2010 Posted October 2, 2014 Share Posted October 2, 2014 Lot of posts say you lose power with decats or hfc unless you have a remap. Quote Link to comment Share on other sites More sharing options...
Bems Posted October 2, 2014 Share Posted October 2, 2014 Fit the nismo, see if its to your liking. If not add HFC's. Simples. Quote Link to comment Share on other sites More sharing options...
GMballistic Posted October 2, 2014 Share Posted October 2, 2014 I have Berks HFC's on my Zed which are fantastic. I did have an UpRev done on my car not long after having them fitted (about two months later) which obviously improved performance but even without that the sound difference over OEM Cats was so much nicer. Just for your enjoyment here is what a Nismo exhaust system sounds like with De-Cats; http://www.350z-uk.com/topic/90016-nismo-exhaust-with-de-cats/ Also fyi ~ I may well be selling my Berks HFC's which have only been on the car for 10 months (4.5K miles odd) so if you're interested I'll let you know when/if I decide to sell them as will be a lot cheaper then the £415 odd new. Genuine reason for sale as I may be going down the De-Cat route due to FI. Quote Link to comment Share on other sites More sharing options...

I may well be interested if you decide to sell them matey if I can get more opinions re, Grahams point (above) on the potential loss of power with HFC's but no remap as I am not interested in remapping at present 1 Quote Link to comment Share on other sites More sharing options...
Kev Posted October 3, 2014 Share Posted October 3, 2014 Don't get HFCs if you're not remapping. Quote Link to comment Share on other sites More sharing options...
Tarmac@TarmacSportz Posted October 3, 2014 Share Posted October 3, 2014 I ran HFCs on my Zed for nearly two years and didn't have a re-map or loss of power I reckon its scare mongery from the tuners Obviously you will get optimum performance from a remap thats no doubt, but you can run without a remap, thousands do 1 Quote Link to comment Share on other sites More sharing options...
