I am interested to hear what you think of it, and the fitting. I did bud yes, before my thread got turned into a sorry state. Anyway, I'll copy and paste what I wrote there and share the pictures. Hopefully it's some use to you, and don't hesitate to message me if you want any specific pictures or videos "So an update for those who are in a similar boat as me with a MK2 Nismo On Monday the Invidia Gemini that I ordered from Tarmac Sportz turned up, perfectly packaged and right on time. Today after work I decided to make use of the workshop and fit the exhaust myself, as why have a dog and bark yourself. I want to say a massive thank you to Bob and Chris at Tarmac sportz for first class service, information and options I will say the Invidia Gemini was not my first choice, which was the ARK grip V2 however out of the box these do not fit MK2 nismo's and require welding to fit, which I couldn't bring myself to do on a £2100 pound system out the box. The welding and design on the invidia is gorgeous, and a credit to them. Removing the old system was a breeze part due to a workshop full of tools and a relatively low mileage exhaust system. Total time for removal and fitting the Invidia was an hour and a half. Fitment is perfect in terms of not hitting the chassis or differential clearing sections including the lower chassis brace and the rear bumper. It's not perfect cosmetically as due to the longer rear on the Nismos the tail pipes do sit shorter in the bumper then ideally liked, however I have been since able to realign them for a better fit. They are on the smaller side for Nismos so could ideally benefit from 5 inches tips in the future. Sound wise it's borderline perfect, with a deep rumble at cruising speed and a lovely tone under throttle. As others have said its everything the Nismo should have been from the factory. Personally, I'd have liked a touch louder so in the future I'll be looking to get the Y pipe baffles removed. Overall I'm very very happy considering the battle us Nismos owners have getting an exhaust. Hopefully with time it'll get a little louder" So that's my write up on the Invida Gemini. I took the car out for a second spirited drive Thursday evening and I do really enjoy how it sounds. I do wish it was a tad bit louder as you can put it into 6th at 70mph and I'd go as far to say its as quiet as OEM, which don't get me wrong isn't a bad thing. Truthfully I'm still looking at exhaust options and I wouldn't be surprised at myself if in 6 months time I've changed again in the pursuit of the perfect exhaust. Ratings wise I'd break it down like so Fitment : 9/10 - a point lost simply to the tips being on the smaller side for a Nismo and sitting a little recessed back, but as for on the car it went on a dream Sound : 8/10 - it's how the car should have come from factory and for the gentleman moder it fits the bill perfectly. Downshifting sounds lovely without it being full of pops and bangs with a nice gurgle and the only drone I've found is going up a light incline at 70mph in 6th, but it's completely bearable. I just wish it was a tad louder for that slightly more "big grin" factory because if you drive it sensibly its very tame Quality Vs Cost 10/10 - the workmanship and quality of the exhaust vs what it cost compared to other manufacturers is probably its best point. The welds, fitment and finish are second to none, many at work were surprised it only cost £1260. They were expecting more. Its extremely competitive in what it can offer without breaking the bank 1 Quote Link to comment Share on other sites More sharing options...
Rhysos Posted March 4, 2023 Author Share Posted March 4, 2023 Thanks for posting that - I hadn’t noticed it on the other thread - my bad! Really like the look of it and from what I’m hearing getting some high flow cats may help with the sound! Definitely food for thought!

GranTurismoEra Posted March 5, 2023 Share Posted March 5, 2023 Are there two Invidia Geminis. V2 is the £1400 one with the blue tips. I think the original is £1260 or something. Its OEM plus for sure. Quote Link to comment Share on other sites More sharing options...

Other then the mid section there seems to be no noticeable differences 🤷 23 hours ago, Rhysos said: Thanks for posting that - I hadn’t noticed it on the other thread - my bad!

My brother in law managed to recorde a pretty decent video today of the car and its definitely louder on the outside then it is in the cabin, which definitely isn't a bad thing. Had a little fun with a skyline as well this afternoon that I bumped into while on a drive and he seemed to approve of how it sounded. Have you had any thoughts of what you'd like to fit?

Rhysos Posted March 5, 2023 Author Share Posted March 5, 2023 Sounds like fun. Definitely going for the Gemini v2, just need to think about whether to add HFCs the same time or run the exhaust for a bit first which I may do, then add HFCs and a Ecutek tune at the same time. That’s the current plan.. Quote Link to comment Share on other sites More sharing options...
Olly350z Posted March 5, 2023 Share Posted March 5, 2023 Having messed around with high flow cats in the past I'm really reluctant to go down that route again, due to possible fitment issues, then having to get them remapped and then possible MOT emissions issues. My previous 350z was heavily modified and truthfully I've not missed the issues that come with it especially every MOT Whats interesting to note on my system and its something I'm giving thought to is the mid section. Currently there are two large baffles, I do wonder what the system would sound like if I got a reputable company to make two pipes that removed the baffles leaving just the large backbox. I'd wager it would up the sound volume quite nicely as the standard cats would do a good job at keep sound levels reasonable and still being able to pass an MOT easily. Maybe I'm growing up but I do like just getting in and pressing the button without warning g lights, rattles etc 😂 Quote Link to comment Share on other sites More sharing options...
Rhysos Posted March 5, 2023 Author Share Posted March 5, 2023 (edited) Lol - know what you mean re HFCs. I’ve had similar in the past as well hence likely to run just the exhaust only for a bit. I will hopefully pull the trigger soon and order the exhaust! Good luck with the thinking on the mid section and if you do get something made, it would be good hear about the results!

pintopete58 Posted March 5, 2023 Share Posted March 5, 2023 Now you paid about 1250 I think and I mine would of bin 1400 + I can't see why so much difference. Bob told me when he fitted mine it's the quite one of the two . Quote Link to comment Share on other sites More sharing options...

Rhysos Posted April 3, 2023 Author Share Posted April 3, 2023 Quick question before I pull the trigger on an exhaust. Does anyone know if changing the cats for HFCs will result in an error code on a 370 Nismo? I am trying to work out whether to do cat back and HFCs then an Ecutek remap in the future, or just cat back for now then HFCs and a remap at the same time.

It could result in a eml but sometimes it doesn't. Both times I have used hfc's I haven't had an eml. However some people do get them, you can but spacers for the sensors which can help.

Jack94 Posted April 3, 2023 Share Posted April 3, 2023 Personally I wouldn't add HFCs without a remap, so would just get the catback done first if it's not an option to just get it all done in one go. Quote Link to comment Share on other sites More sharing options...
Olly350z Posted April 3, 2023 Share Posted April 3, 2023 I had an EML when I did HFCs and injen exhaust on my old 350z, I became very familiar with the pedal dance until I got the remap done Quote Link to comment Share on other sites More sharing options...
Rhysos Posted April 3, 2023 Author Share Posted April 3, 2023 Thanks all. Cat back it is then as first step! Looks to be the safest option 1 Quote Link to comment Share on other sites More sharing options...
