personally I think decat may increase the gains by aleast 10bhp, even over a sport caT which id only ever use it for MOT. If I put a sports cat on my Super charged FN2 I expect I'd lose at least 20 BHP. If I can hit 360bhp On a 370 i think I'd be satisfied for a while and can focus on making the car look and sound good !

I don't even get what the left side of the chart means. A stillen Gen 3 is the only intake which is proven to give gains being a true CAI. I think they claim 12-18 BHP or so. I wonder if I could get away with lowering one if I buy one 🤔 Sent from my iPhone using Tapatalk

These look fantastic on a red car similar to my Rays if I didn't already mention ! Red strips can be unpopular but they look so much better bin person believe me ! Sent from my iPhone using Tapatalk

What's the ideal to have on these and to clear calipers ? Thanks guys Sent from my iPhone using Tapatalk

Guys I am due to view a GT Edition 11 plate on Saturday, would people say it's worth the premium over the regular GT? It has the vinyl on the side, dark silver alloys and apparently the suspension and other bits are revised. I still prefer the alloys in black though. What do we think, is it worth it?

It seems that what I want is a HFC or decat which is resonated. But furthermore, the Helmholtz chamber which elinates certain frequencies. Likewise with a CAt back, ark Grip and motordyne shockwave use the same technology, yet are not particularly quiet as cat backs come. The Motordyne ART pipe is definitely for the win. If you simply want to reduce the noise then any resonated decat m/HFC is ok. Just look at the size of the fast intentions HFC resonator, it's pretty big. Yet this is the ART decat I would ultimately be acquiring The motordyne shockwave cat back used the same principle although it's not particularly quiet. It takes away enough of the bad frequencies though. The Ark Grip uses the same Helmholtz chambers yet has additional silencing so must be quieter than the shockwave I'll post a video of the sound I'm trying to achieve soon.

Can't be 400bhp lol Sent from my iPhone using Tapatalk

Nvm I've decided the best sounding BY FAR is the motordyne shock wave band the motordyne decat ðŸ‘ðŸ‘ðŸ‘ðŸ‘😎😎 Sent from my iPhone using Tapatalk

I'm posting this in here too: Hi TORQEN & other traders. What's the best price you can do on these? As I'm guessing they must be the quietest best performing resonated decat pipes you can buy? But if I'm wrong please correct me. I'm thinking that logically the larger the perforated silencer the quieter it will be l. Below is the motordyne decat. And then this is a resonated fast intentions high flow cat which I think would be a quiet HFC, perhaps the most. Who can give me the best price on the motordyne decats ? I know ARK do a similar version but their Helmholtz chamber things look shorter. I'm also assuming that Helmholtz chamber is for effective or sounds better than your typical straight through silencer. That's what I'm trying to determine. It's really complicated this @*!#, trying to produce the best and balanced sound Sent from my iPhone using Tapatalk

As said I'm potentially going to view this car, it has stillen gen 2 intake and the stillen cat back both installed by the previous owner. I was wondering if the previous owner was on here as it sounds rather loud like it might also have a high flow cat Thanks Sent from my iPhone using Tapatalk

I would recommend a resonated version to keep the noise levels down. I do not see how they can justify over £500 for two very small sections of pipes but that's the only option I'd consider. How much can you sell the ark resonated decat pipes for? The ones with their special resonator chamber, as id probably run this all year round with a remap and buy cheap EBay HFCs just for MOT time. Sent from my iPhone using Tapatalk

I'm very particular when it comes to exhausts. It needs to be quiet and refined enough yet still loud enough to open up the melodical engine note of the V6. I dont normally buy cheap stuff but in the case of decat pipes it's such a small section of pipe, as long as the welds and OD is good I don't see any problem. I've found some cheap resonated decat/test pipes and some cheap high flow cats. I'd purchase the latter purely to swap over for MOT and remap the car with the resonated decat pipes for maximum power. If I achieved 360bhp I'd be very pleased. If that's still too loud for me I'll have 2 smaller silencers added in the system which wouldn't cost more than £100 or so.

I think I'd stick with CBE until I can find a cheap or 2nd hand HFC with resonators. Then before mapping I'd find a decent decat, again with resonators. There seem to be some cheap alternatives to the bigger brands and being that it's such a small section of the exhaust I don't see why the cheaper versions sound perform any worse than the £500 berk HFCs or however much they are Sent from my iPhone using Tapatalk

Got any driveby vids? The ones I've seen are so loud you can hear them a mile off and in a built up area they reflect off everything and so loud you'd gain the attention of pretty much every pedestrian just by going above 4000 let's say. Sent from my iPhone using Tapatalk

The high flow cats seem to be the best single mod for gains. I stillen gen 3 intake would also give some gains. Remap is the last thing you want to do after you've completed your mods Sent from my iPhone using Tapatalk

Jet pilot can we not just agree to disagree? The stillen intake & cat back are claiming 10-20bhp each and that is relevant to me, even if you don't care what they make. The X note sounds interesting and I wish there was more info to back up the claims. If everyone says it's the best sounding exhaust then it probably is, and that's the kind of definitive info I was looking for. I do think of the 370z. An make over 30-40bhp with mods and remap then that's certainly worthwhile for me Sent from my iPhone using Tapatalk

Oh come on I'm not new to the modding scene, I did supercharge my FN2 I know all this anyway but I was still interested in the gains, but it seems not any care about it. It is important though, there can be a fair bit if difference between the best and worst induction kit (for example). Different dyno s, different engines yes. I know. Even different ambient temp on the day. Yet still on CTRO we've managed to establish which are the best performing mods! You can pretend you're not so bothered but then you would be if it turned out the ARK GRIP consistently made 10bhp less than its rivals! Dyno figures sell a lot of products. Anyway if u wanted all out performance I'd have stuck with the FN2. But I like the other characteristics of the 370, namely the engine and sound of it. Also the looks. Plus I'm looking forward to doing some 1st gear launching which I can't do on my FN2. I'd probably go with one of the resonated HFCs for now and swap it with resonated decat when I go for remapping, depending on how restrictive 2x 200 cell cats turn out to be. I guess there's no point asking you guys this question but on a K20 even one sports cat would probably lose 10 BHP over a decat. I'd love to find out more about the dual X flow chambers, it may be legit, probably is but it sounds a bit like a gimmick. I've had 3 different custom cat backs. First one with longlife and then two from solid fabrications. I did consider a whole new system but it would be much cheaper to get a stillen modified slightly. It would be done in a very professional way, the fact is, I think with any HFC or decat it would just be too loud. But I've not heard the resonated ones so I may be wrong. All I can do is search you tube. Sent from my iPhone using Tapatalk

I like to know that my performance is maximised and so my money is well spent on mods that provide the best gains possible. If 360bhp is the most I could get on a 370z then so be it, but if 370 were possible then I'd be happier 'chasing' that figure, whether it's significant or not. We don't utilise the power all the time when driving but just knowing what it's capable of is half the fun. And to me, 20bhp/lbft would certainly be worthwhile and perhaps just about noticable. If I was only interested in performance then I'd stick with my civic, which is a fair bit quicker already than a standard 370z, or even a modded one. But if I'm to change to a 370z then I'd want to extract as much power as possible, which is what I'm trying to determine at the moment. But I'm guessing nobody has done back to back comparisons of the cat backs, so I'll just have to make a guess. There's probably not more than 5BHP difference between them anyway Sent from my iPhone using Tapatalk

Well that's interesting that they're resonators but these would cause back pressure on a 2.0l NA. Pub figures or not, I do like to know what BHP each mod is making and if I had that care free attitude to each mod on my car then gains would be entirely irrelevant! Of course there is a difference between 357bhp and 373bhp, it's not a great deal and you'd struggle to notice it but it is a significant difference. I figured someone might know the performance difference of the two exhausts and what effect that dual chamber design had. On type R forums it's pretty straight forward and through dyno evidence we've learned which mods perform better etc, even if the difference is minor. A combination of superior mods can result in a more significant gain. I think I'd try one of the resonated decats if I wanted all out power. An ARK would be great but I cannot see myself buying one brand new, well not just yet Sent from my iPhone using Tapatalk

Hi guys I've been researching what kinda setup I'd have on a 370z. Because for good power I'd need the stillen intake, some brand of HFCs and an after market exhaust. Is there anything else? I might one day try decat pipes too if the gains were like 20bhp over the HFC, but I'm guessing it's far less. Horsham developments told me the highest figure they made on a 370z with decat/test pipes, a cat back and intake is 357bhp. Is this true, or has anyone achieved better than this ? Secondly, after watching many YouTube videos it seems that with either HFCs or an aftermarket cat back alone, it improves the sound and volume dramatically yet still remains refined. But add both of them together and it becomes too loud, subjectively speaking. But most would agree it's a bit too loud and approach WOT and you'll really let the whole street know about it. It was the same @*!# with my EP3 & FN2, the aftermarket cat backs are designed with consideration that most owners will not use HFCs or worse, a decat. They may actually be the same in volume if the HFCs do not have any resonator or deadening, I do not know. So my plan was that if/when I got HFCs I would go to a custom place and add another two smaller silencers in the cat back system, they wouldnt be huge but enough to reduce the volume/decibels by 10-30%. At least 20% to be worthwhile it's quite possible to do so on a stillen car back as they appear to have the space. Other systems may not, without having the whole section redesigned. This should get it to the levels of a system with only either HFCs or a CBE, but not as overwhelming as both. And I know different CBEs vary slightly. The next issue I have is, ARK GRIP and HKS power have opted for like a second silencer where the piping is blocked off. Two of them. I guess the idea is that the gas/sound flows into there and out again, some of it being reduced before coming out of the exit pipe. As I understand, this is considered to be the best sounding exhaust, and the disruption in flow and exhaust pulses may enhance the sound, much like unequal length headers create a nice burble. HKS also sounds prettt nice and it's the exact same principle. But surely this design must cause back pressure? on K20 systems any back pressure results in loss of BHP, if only 2-5 BHP and at the higher rpm. Is the regular straight through design of the stillen not proven to be superior? I don't pretend to know about this engine but that's how it works on the K20 so it made me wonder. Has anyone done any comparisons? There may be other factors involved too such as the pipe diameter, routing & quality of bends, welds etc and it could even be that the ARK GRIP is simply slightly louder and people assume it sounds better because of this. P.s I've just realised they refer to it as an X-flow or dual chamber so I'm going to research what they claim this does !

It's actually up for £13,490!Which may be realistic if I'm willing to be patient this time of year, but I'd be more likely to sell at £12,500 which is getting towards a bargain IMO when some stock low mileage CWs are selling for up to 10 standard lol Sent from my iPhone using Tapatalk
