ryanbatch Posted May 25, 2016 Share Posted May 25, 2016 Hi guys I could use a bit of advice if you don't mind. Recently bought a brand new invidia Gemini from tarmac and had it fitted by a trusted local garage. Sounded amazing, a deep roar especially at lower revs, then sounded great when I opened it up a bit more too. The past couple of days I have noticed that this amazing deep tone has faded away. The exhaust seems all round quieter, and much less throaty and deep. It may be starting to bed in but I was advised by really everyone that once it begins to bed in it will sound better and even get a little deeper, not the opposite? It now doesn't even sound- dare I say it- that much different to stockðŸ˜. And it certainly did when the thing went on. Thanks in advance for any light that can be shed on this Quote Link to comment Share on other sites More sharing options...
Ekona Posted May 25, 2016 Share Posted May 25, 2016 Either you've got used to it, or it wasn't fitted properly and the gap has now closed itself up Could well just be where's it's coked up and changed tone. Quote Link to comment Share on other sites More sharing options...
brillomaster Posted May 25, 2016 Share Posted May 25, 2016 the tone will change as it cokes up inside. when my cobra was brand new, it was quite loud, and a harsh, metallic noise. once it had a couple thousand miles on it it sounded a lot more mellow, which I preferred.

ryanbatch Posted May 25, 2016 Author Share Posted May 25, 2016 Aghhh! Very confusing. Everything that I'd read online and watched online about how its meant to sound seems consistent with how it sounded when it was first fitted! And haha also realised that I will become used to it- but others have noticed the difference too. The sound has changed in the complete opposite way that everyone said it should when it cokes up Sent from my E5823 using Tapatalk Quote Link to comment Share on other sites More sharing options...

Thanks for the reply. I was certain that the way it sounded when I first had it fitted was "right". Now it just doesn't Sent from my E5823 using Tapatalk Quote Link to comment Share on other sites More sharing options...
Richf Posted May 25, 2016 Share Posted May 25, 2016 Stainless systems always mellow after a bit of use Quote Link to comment Share on other sites More sharing options...
ryanbatch Posted May 25, 2016 Author Share Posted May 25, 2016 Stainless systems always mellow after a bit of use I did expect a sound change but it seems to have lost its tone, and as I said I was told to expect a deeper tone, not a miraculous change back to stock noise.

350zedd Posted May 25, 2016 Share Posted May 25, 2016 You wouldn't have had that problem if you'd bought an ARK 3 Quote Link to comment Share on other sites More sharing options...
brillomaster Posted May 25, 2016 Share Posted May 25, 2016 if its not what you were expecting you'd still be able to recoup most of the cost if you take the invidia off and sell it on - perhaps a K1 is what you need! Quote Link to comment Share on other sites More sharing options...
ryanbatch Posted May 25, 2016 Author Share Posted May 25, 2016 You wouldn't have had that problem if you'd bought an ARK Hahaha oh for god sake don't!! That was the other one I was considering Sent from my E5823 using Tapatalk Quote Link to comment Share on other sites More sharing options...
Tarmac@TarmacSportz Posted May 25, 2016 Share Posted May 25, 2016 They all calm down a little after they get coked up, plus you do get used to them pretty quick. I've got HFCs and they do make a difference to the sound if your wanting more, so do decats Quote Link to comment Share on other sites More sharing options...
cs2000 Posted May 25, 2016 Share Posted May 25, 2016 Agreed, my N1 needed an ASBO when it was first fitted!! Its still loud now mind, but it has softened a bit. Quote Link to comment Share on other sites More sharing options...

Hahaha how much use before it softened? Mine has changed quite dramatically in just a week, and I don't do mega miles either Sent from my E5823 using Tapatalk Quote Link to comment Share on other sites More sharing options...
kbad Posted May 25, 2016 Share Posted May 25, 2016 Agreed , I had my cobra resonated catback fitted at CS 2 weeks ago and its certainly mellowed ( to mine and my neighbours liking) Quote Link to comment Share on other sites More sharing options...

SHEZZA Posted May 25, 2016 Share Posted May 25, 2016 I can't say I ever noticed mine mellow, though i did have Berks hfc's fitted from day one. If anything it got louder ! Quote Link to comment Share on other sites More sharing options...
delz0r Posted May 25, 2016 Share Posted May 25, 2016 Mine got louder as it bedded in for sure. But you do get used to the sound increase very quickly. Quote Link to comment Share on other sites More sharing options...
GMballistic Posted May 25, 2016 Share Posted May 25, 2016 Sure you're not just going deaf Ryan? Had Berks HFC's with my Invidia system on my Zed and later the Berks De-Cats, ...both brought out the beast from the Zed. 1 Quote Link to comment Share on other sites More sharing options...

Definitely quieter than when it was fitted, and lost the deep roar!

Hahaha I think my hearing is actually still okay I think those are options I'm now gonna need to consider! Sent from my E5823 using Tapatalk Definitely worth considering. Worth noting though that the downside with both those options though is that unlike the standard Cats you will fail the MOT emissions test for definite with De-Cats and it's touch & go that you will pass with the HFC's. My old Zed passed the MOT emissions test no problem with the Berks HFC's I had fitted but I know other members with an identical exhaust setup have failed in the past. You can get around this one of two ways ~ either you are friendly with the MOT guy or you put the OEM Cats back on for your MOT each year which some people do but I'd personally find that a PITA, .....or you're one of the lucky ones like me who had HFC's & still passed the MOT emissions test.

Thanks for the info! Yeah definitely I did a bit of research on decats/HFC's previously. I know enough friendly MOT guys haha And great video! Have watched that before on YouTube but didn't realise it was you! Car looks and sounds like a monster!

Sent from my E5823 using Tapatalk Cheers Ryan. It was a great car but sadly I had to let it go around a year ago as I was buying my first house with my fiancee. Needed something slightly more sensible for the Ikea runs & move in day. Take a look at my build thread here though if you want some inspiration or just to see what else I did to it: http://www.350z-uk.com/topic/91628-gmballistics-zed-supercharged-2003-gun-metal-gt-coupe-vids-added/ More videos of it here: https://www.youtube.com/channel/UClRmiU_ciZ6yuBPT99e4Niw Quote Link to comment Share on other sites More sharing options...
