The £5,500 Lotus Titanium Exhaust - Loud Noises and Comparison with Standard Stainless (Evora/Exige)

- เผยแพร่เมื่อ 20 ก.ค. 2018
- With the Evora Sport 410, Lotus introduced a very expensive option - the Titanium Exhaust. Identical in design to the standard item, but 10KG lighter, people have since been talking about whether this sounds different or not.
So, with the help of my friend James and his Exige Cup 430, we are going to do a semi-scientific comparison of the Titanium and standard exhausts.

Love the channel James , that is one expensive exhaust but it's something to brag about in the pub I suppose 😉👍
They both sound bloody awesome 👍😁.
Thanks for the videos James.
The noise level will also change with temperature- something to bear in mind (back pressure changes too).
It can also be difficult to separate exhaust noise from intake noise etc. and subtle changes in wind direction can also make a difference.
NVH is very difficult as it’s so subjective too - louder isn’t always worse preferentially but the sound meter can say differently!
5.5k that's about 11k in our money nzd ...no way it's a swindle bro the 400 sounded better anyway IMHO cheers James
Cracking buddy ! 😂👍
Both sound lovely! The Evora 400 (yours) having the valved exhaust is better for crawling relatively quietly through towns. I kind of like that, especially given it sounds so good when the valves are open.
Thanks for posting.
Thanks
Great stuff, great idea James. I am going to keep my steel exhaust then and spend the money on gym membership, that should get me the same weight loss. Lol. Love both cars.
For reference he didn't option this exhaust, it is standard on the 430
amazing! great comparison and i would be pisssed off about speccing a titanium exhaust on my new Lotus (when the time comes!) :)
Always interesting to know these things, thanks. I personally dislike the blueish hue on Lotus' Ti exhausts but not as much as I dislike the con price (for what it sounds / weighs / power hike). Always watch for con options...
I think I prefer yours James, but I'd happily have either!
These videos get my vote all day long ie, no mention of any long-term loaners from audi uk, if you get my drift ;)
Can I get an opinion on the best 'Track friendly' exhaust, or modification for a Exige 430 Cup? I have a car in stock currently with the titanium option, and from what I understand (from your other videos) these are an issue with noise regs at most track days? Thanks, Ed
They sound different but I like both.
I believe the key reason to buy the Ti exhaust is the weight savings. While the price isn’t cheap Ti is both expensive and very hard to weld. To me the only real world benefit of this option is bragging rights as reducing my drive time to work by 0.000001 second is difficult to quantify.
They'll also output sound differently under load.That's perhaps due to the additional fuel and bigger bangs required to make actual motive power. But I think this test does a good anecdotal job of demonstrating the differences. I suppose a reason for variations in tone are due to the different frequencies at which the materials and their varying masses cause the systems to resonate. I'll keep the cash, thanks!
A run through the gears would have been nice. On my way to but a Camry V6!
They both sound awesome. I think maybe the Evora has more of a raspy sound, but that's about it.
New subscriber to your channel from Toronto Canada. I’ve been enjoying your videos tremendously. I’ve lusted after an Exige for years but they’re quite rare on the ground here and haven’t been sold here new for some time. I’m a bigger guy at 6’4” and after watching some of your vids I’m thinking an Evora might suit me better. Can I ask how tall you are?
Also, I think the exhaust on your car sounds fuller and richer than the titanium setup and seems a bit louder to boot.
Looking forward to more of your content!!
Welcome to the channel Chris. I am not that tall but with the seats I have in the car my 6' 7 friend fits easily
JayEmm on Cars That’s great news, thanks 👍🏻
Its an $8k USD option here in the states, better off getting that $250 cat delete pipe
They definitely sound different, will be interesting to see how the 430 changes as it gets some miles under its belt. Revisit this in a couple thousand miles!
Yes it will be interesting to see if it becomes closer to the Evora, or something else
THE TITANIUM ONE SOUNDS DEEPER,THATS WHY I PUT THE SPORT EXHAUST ON MY BMW M4 M SERIES I BOUGHT THIS SUMMER!!!
They both sound absolutely amazing, but the Evora sounded sharper
You are closer to the evora 400 you should have put the mic on a tripod the same distance away from both
Your Evora sounds louder on video. The pitch is higher.
Felt louder in person, but it was a lot bassier. The sound went *through* you
I went driving with an Exige 410 sport with titanium exhaust and I myself have the Evora 400. The Exige sounded mich more aggressive but mainly because it has a lot more pops and bangs compared to my Evora. EU cars so no 3th cat like the US. Probably it also sounded more aggressive since I drove the exige without the roof, but certainly more pops and bangs 100%
Titanium has raspier sounds due to its lesser mass. i prefer the sound of the stainless though but extra 10kg weight saving is great for a cup car i think.
When you told your mate " I think mine is louder", he yelled "Really?" and think "I am f*king regret to get the Titanium exhaust"
Is it available for the exige sport 350?
I have the former Lotus America corporate Evora GT. It has most every option except for the titanium exhaust. From what I know, the only difference is the 20 lb weight difference. The sound is basically the same. I do not think this is worth the $8,000 cost. If I want to save 20 lbs, I can always remove the useless rear seats. Now, I have added the GRP decat and cold air intake. Those changes make my great sounding machine an even greater sounding machine.
Now I don't know if the engine is entirely the same, exhaust piping, etc but for the sake of commenting lets say only difference is the exhaust itself (same exhaust shape), stainless sounds more muffled "contained" while titanium sounds more "treble" like. Same note but with treble frequencies enhanced.
Both do sound lovely though. Would rev either and feel like a child every time.
Very similar, the Evora a bit higher pitched and raspier, which I like a little better. Certainly wouldn’t pay that kind of money for the sound alone.
The money is in the weight loss and power gains I would have thought. Sound will be marginally different as the metals are different so the actually structure will be different
decibels are logarithmic 93db is twice as loud as 90db
Why didn´t you do a flyby noise test. It would be much more representative. And yes Lotus exhaust changes massively after they are run in. My Exige350 flyby noise was 114db 2.gear standing About 2m away (stock exhaust). Now I changed to KomoTec back box...will test soon the noise difference (it is louder for sure).
True. Guess I'm biased as I do build Lotus for a living.
The titanium exhaust is not the sound completely the change but the weight and the heatsink of the motore that can help the function of the motore helps to maintain the motore oil will not brucia because titanium more faster to get cold like any other steel. And faster to get hotter also. That's why titanium materials specifically in the exhaust and muffler is more advantage than any materials.
the titanium is 40% lighter compared to stainless steel; however the majority of weight (and noise reduction) in a muffler is due to the amount of fibreglass packing (or stainless steel wool packing) used in the muffler. So you could have a stainless steel muffler, with less packing (and hence lounder) than the titanium muffler. The very light titanium systems also have very little packing, and hence are very loud (usually the japanese brands). Its the muffler packing material that makes the difference to noise and weight.
The factory stainless exhaust has ZERO packing materials.
How much weight can you save when the engine is rear/mid mounted? I'd trouser the £5k and buy something worthwhile.
Lotus claimed 10kg
I always thought they tested the dB meter much closer to the exhaust pipe. When I go to the track they seem to stick the pole right behind my muffler maybe 1-2 feet away. I don't for a second believe those cars are only hitting 94-97 dB when mine is super quiet and hits about 92-94! Also, stainless sounded better but maybe because it is more run in.
Yeah I was too high, my car as mentioned registered 111 at Snet.
Usually at a 45degree angle to the exhaust and at the same height - 1-2 feet back
Andrew Austerfield yes 1m away officially I think. My method was not intended to be the same as theirs just the same between the two cars. The meter and my ears agreed
I'd spend the 5.5k on something sensible like wine gums and prostitutes.
Sounds like a good plan to me.
In fact, forget the wine gums!
Good efforts Jay. But just buy a 2bular :)
umm - yeah - I'd go along with that !
I’d struggle to tell the difference. Certainly not worth the money.
The lighter exhaust will make the car faster and handle better. It makes a big difference the weight to a Lotus
im my opinion the evora sounded louder and nicer :)
Almost identical sound, the evora is louder but you look closer to it so maybe that's got something to do with it.
Evora is a different tone of sound, feels louder
5.5k!!!! Absolute robbery
Eh, titanium is about 6-10x more expensive than stainless steel for raw materials. So that'd place the stock exhaust in the 550-950 range assuming it's stainless. Looking at replacement costs it's right on with cost of materials.
Plus you need a welder with a special license to weld the stuff.
Has to be TIG welded and titanium in general is a total PITA to work with.
I know the costs as I sell the raw materials both stainless and Ti
After a good few years in that very trade James I can say that to manufacture a titanium exhaust is a far slower process because the material is stronger yet thinner etc and without wasting a few minutes of everyone’s life I will leave the process there. The saving is weight and bragging rights at the bar😁 but if you know who to talk to or where to look 👀 you can buy a titanium for the same price you can buy a stainless.. and a stainless for the same price as an Oem... wiki.seloc.org/a/Exhausts_-_Evora#Lotus_Sport_Stage_1_Exhaust
Titanium exhaust sounds more refined than steel but steel is louder and heavier than titanium.
still with these shirts !!!! .......... wear ear protection with noise at 90decibels and over
Always with the shirts :)
Oh, n I prefer the evora's noise
The one on the right is deeper sound and the one on the left is louder
If you're struggling to get another .10 off your 1/4 mile or a second off aggressive lap times, go with the Titanium -- else don't waste your money unless you've got Titanium laying around.
Your not paying the money for the sound alone, it's the lightness and if you heard the flyby at goodwood of the exige you hear the difference.
I've heard this fly by a few times
for the money spent id probably buy magnesium wheels if any were available
The existing wheels on it are already forged and very light
James, sadly this is the first video I've seen from you where the camera work leaves me feeling a little unbalanced, almost queezy. I know it's difficult to produce such a video otherwise, but it'd have been better with someone else holding the camera or using a tripod. As for the exhausts (which is the important thing here) I'll go out on a limb and say I preferred the tone of the Ti even though I think the volume was about the same. 5.5K? Isn't that about the going price for Ti anyway? They will last much longer, I think getting on for the lifetime of the car? The sales arguments for Ti are much more than "it sounds better / louder". As an aside what decidel ratings do your two cars have? I know they're both legal as they're 'stock' and not after market options. Here in DE the Police are really keen on pulling cars off the road which have what I'll call "after market extra volume". They know what the car is rated at (db-wise), test at the roadside and if you're over then the car is immediately impounded until you get it transported to a workshop and corrected. Complete with all costs of impounding, transport, repair, new TÜV (MOT) to guarantee compliance and of course a fine. Sorry for the long post.
Keith, we are working on solutions to make solo camerawork smoother but it's never as simple as it seems. Thanks for bearing with us.
Sure and as this was a shorter one it was OK. Back with the exhausts ...... I took the Akrapovic option on my RS and the stupid salesman tried to tell me it was Ti but no chance, it's stainless. Also interestingly the UK option price for it is 900 GBP, here in DE €1900 for the same thing. Ouch, but nice.
Wow normally we are the ones getting shafted on price. Interestingly I was told Germany does not take anywhere near as many options on its cars as we do
Interestingly I checked what I paid for mine and if I'd ordered the same spec & options in the UK the price would have been very similar. I paid a good double the UK price for the Akra, but less than half the UK price for leather interior. Swings & roundabouts. Each country decides their own 'standard' configuration and option prices. UK offers reversing camera as standard, it's an option within a package for us and pretty expensive so that's the one option I didn't include. otherwise fully loaded.
I’m missing something with the comments. Do people go the upgrade because of perceived sound differences? I thought they’d be more important reasons for the upgrade?
Lightness, the tip looks cool, those are the only real differences I can see. I had hoped when it was announced it was the much needed track exhaust, but it is no different to the normal system
JayEmm on Cars yes that’s my point to the “sounds no different what a rip-off type comments”, people going the upgrade aren’t likely to be doing it for the sound but more for the 10kg weight saving (and maybe also added status of having titanium exhaust).
I suspect telling people you have a titanium exhaust is more important than it being actually lighter for most. I doubt that anyone could really tell the weight saving unless you were an incredibly skilled driver, on a race track.... where the exhaust is too loud anyway!
JayEmm on Cars but as part of a complete weight saving package it’s a significant weight loss. Hey what’s the first thing we think after we purchase one of the lightest cars known.....make it lighter ;).........oh and 100% agree with the noise track day issue :(
Yep, I just think Lotus got it wrong by using the same design. If this was track legal, it would have made a lot more sense to me
Evora hands down......
yellow one has a lot more rasp
Almost identical so not worth £££
Yeah, you could save more weight and money by just leaving the mrs at home.
Are you the brother of shmee ?
In terms of performance, absolutely not worth the cost. For that kind money could buy or build NA 2ZZ (or whatever engine they're using now, I guess it's a 6cylinder in the Evora) to be an all out racing engine or put one hell of a turbo system on what you have now and (with lower compression/better rods and studs, forged pistons) double your horsepower. But if you're desperate to shave off every last pound off an already featherweight car (and off your checkbook) then sure, I could see it being worth it to someone.
£500 Larini on my Elise is droneingly loud 😳
The Larini on my 111R was the same. I sold the car with a factory exhaust to replace it and when the new owner took the Larini off it had apparently split in two places! So much for their famous quality
Yeah I went for the Clubsport - can be tiresome after a while ;)
@@JayEmmOnCars What famous quality is that then?
No spare tire or jack, what's up with that? No towing service or loaner car either ?!?!?!?
Evora does it or me.
Doesn't sound like you are losing out aurally by having a standard exhaust, much cheaper to eat a few less pies to lose 10kg too.
Video starts at 3:28
Well, Cletus, I'd say the Evora is the baritone, and the Exige is the tenor. Their common ground is they are both ear shatteringly loud. Now, if you'll just hang on for a second whilst I climb up onto my soapbox, I'll continue. Noise pollution, and its concomitant increase in stress levels, is a major problem in modern society, and being deafened by thrill seekers butters no parsnips in my aural books. I do, however, love the sound of my own mixed metaphors.
On a purely subjective level, your Evora looks and sounds much nicer than Jimmy's Exige.
P.S. " Tiny, little boner's video "⁉️ There's absolutely no need to get personal‼️🤨🤨🤨
Noise pollution is an issue for sure, and I like to think I am responsible with my enjoyment of my car. It's never in loud mode late at night etc etc and I don't rev it in town like an idiot (eg. the Knightsbridge crowd).
Living in the countryside, I find it amusing that people with loud cars get lots of stick when the reality is they disturb me for maybe 10 seconds in the day, but people have no issue when a neighbour decides to have a tree cut down at 8am on a Sunday morning.
Cletus, I'm sure you're the very soul of probity and consideration, but you're not the only driver on the road, and, for as long as there are cacophonous exhausts, there will be individuals hellbent on others hearing them.
The disturbance caused by the chainsaw is also due to its loud exhaust,
Notice he blurred the results. I’m pretty sure this guys in the banking industry.
Lol, that's my auto focus being crappy
Not 5k diff. Swap the pulley out w/ that cash.
Stainless steel slightly louder and better sounding.
Is it the entire line or just the backbox? If its the latter it really is a rip off and utterly useless. If its the former, its good value!
Just the backbox!
Instead of pushing people to buy very expensive options (titanium, carbon), which have a quite marginal impact and require no particular engineering from Lotus, Lotus ought to dedicate proper engineering on improving the fundamentals of their cars (eg, steel tubes for the wishbones on the Elise & Exige, lousy gearboxes limiting torque, heavy and thirsty engines, chassis set-up, etc...) so that their cars perform up to the Lotus legend (not the case anymore, sadly).
I suggest trying some of the new breed cars. Yes there are elements which can be improved, but they are far more than the sum of their parts
I'm really not sure what 'Lotus legend' you are referring to, I'd love to know though. The modern cars are far superior in EVERY way to what came before. Sure, there are ways they could be improved but that will inevitably increase the price. There's no point making cars no one can afford to buy. The options list, is exactly that. Each buyer chooses how much extra they want to pay for their car and Lotus make additional profit out of it. Most companies need to make profit to stay in business and develop new vehicles.
The issue is that Lotus presents as performance advancements the addition of expensive parts provided by suppliers (carbon / titanium bits) which is quite sad because none of that involves top-class Lotus engineering. We would rather have innovations and improvements through Lotus engineering, not some fancy and expensive parts provided by suppliers. They increase the price of the cars which make them quite uncompetitive for what they really are. For example, an Alpine A110 is arguably as innovative as a Lotus Elise and yet is significantly cheaper than a well-specced Elise Sprint 220 or Cup 250, both slower cars on the track according to tests performed by the press on the continent in Europe. Also, an improvement in the consistency of the set up of the cars out of Hethel would be a great plus. These are issues ad expectations well kown and shared on the continent in Europe. Perhaps the dedicated followers in the UK look at Lotus with too rosy glasses, and Lotus rewards them by selling them cars at a discount (listed prices in the UK about 15-20% less than listed prices on the continent)
Plse refer to my answer to Andrew's comment below.
PS. Can we have the actual sale volumes released?
Look like shmee150
The Evora sounds better
I don't hear £5.5k worth of difference.
Evora sounds better.
