57jam89 Posted December 12, 2018 Share Posted December 12, 2018 Hi all, I just fitted a invidia gemini with berks test pipes and as it's a daily i finding it just a bit too noisey. So do I swap the test pipes for hfc or art pipes or std cats. Thanks Quote Link to comment Share on other sites More sharing options...
reeceybeaney Posted December 12, 2018 Share Posted December 12, 2018 I think you'll be a little bit disappointed butting standard cats back in, a lot more restrictive too. If budget allows... ART pipes everytime! Quieter than a lot of hfc, retain performance benefits all round too Love the sound of my cobra matches up with ART pipes, best thing I've bought Quote Link to comment Share on other sites More sharing options...

Yes don't want to refit factory cats so it's hfc or arts. Quote Link to comment Share on other sites More sharing options...

Luckily I picked up the arts second hand so got them relatively cheap! A lot of people have told me that, it gives off a great sound rather than just noise Quote Link to comment Share on other sites More sharing options...
PPod Posted December 12, 2018 Share Posted December 12, 2018 True less rasp with art pipes that's why I love mine Quote Link to comment Share on other sites More sharing options...
57jam89 Posted December 12, 2018 Author Share Posted December 12, 2018 So arts are definitely quieter that hfc? Quote Link to comment Share on other sites More sharing options...

Adrian@TORQEN Posted December 12, 2018 Share Posted December 12, 2018 Why, they're empty pipes, with a side chamber next to it, Helmholtz resonator. It reduces the raspiness and vibrations, but not the noise. HFC have 200cel cats inside, the sound gets dampened a bit. Quote Link to comment Share on other sites More sharing options...

True story I tested my invidia with de cats next to my mates invidia with art pipes and there was 1/2 db in it Much deeper tone from the art pipes tho Quote Link to comment Share on other sites More sharing options...
ASemper Posted December 14, 2018 Share Posted December 14, 2018 I added ART's to my ARK grip with standard cats and would do it again in a heartbeat. Great addition in quantity and quality of sound but easy to daily at the same time (at least for me). I have no personal experience of other decats or HFC but do love the ART's.
