hairyman68 Posted June 5, 2015 Share Posted June 5, 2015 Hi currently have a cobra resinated system on. But it's not quiet at loud as would have like. Have read that de cats will increase the sound. Question is go resinated de cats or straight cats..? How much louder will be..? Thanks. Quote Link to comment Share on other sites More sharing options...
GMballistic Posted June 5, 2015 Share Posted June 5, 2015 (edited) Have you thought about HFC's (High Flow Cats) instead? That way you'll more than likely still get through the MOT as with the De-Cats you won't unless you've a friendly MOT guy of course. I've had the Berks HFC's previously on my Zed and now Berks De-Cats ~ I only changed from the HFC's to De-cats as my Zed is now supercharged and it would have killed the HFC's. The De-Cats are considerably louder than my HFC's were and it's also a different kind of sound now. It's hard to compare the two really though as my car is supercharged now which it wasn't when I had the HFC's on. Little video below of my Zed with the Berks De-Cats and Invidia Gemini exhaust system.

Z-Boy Posted June 9, 2015 Share Posted June 9, 2015 Hi I have HFC's, Stillen y pipe and Cobra Non Resonating centre section and that is very loud and sounds meaty. Keith Quote Link to comment Share on other sites More sharing options...

Keith I now have pretty much the same set up. At 3k rpm it sounds like a maniac! I'm not 100% sure I like it. Bit too raspy for me. Will see if I can get used to it. Reminds me of a M3 on steroids!

Daveyboy11 Posted July 2, 2015 Share Posted July 2, 2015 Forget that, keep the cats in and have my K1 exhaust off me and I'll buy your Cobra that's proper noise! Quote Link to comment Share on other sites More sharing options...
veilside z Posted July 2, 2015 Share Posted July 2, 2015 De cats will give you the sound you are looking for. Quote Link to comment Share on other sites More sharing options...
