I might be wrong, but I doubt changing the exhaust would lead to many warranty claims being rejected; it's not like there's much down-stream of the exhaust to be damaged by it. I think they'd struggle to argue that changing the exhaust caused any sort of engine damage.
I fully agree that it should be compliant from the factory though. It's a truly idiotic oversight if it's not (although one which is hardly unique to Lotus).
Agreed, and I think/hope that Lotus would be pragmatic should such a circumstance occur. The Toyota V6 is a robust lump in any case.I fully agree that it should be compliant from the factory though. It's a truly idiotic oversight if it's not (although one which is hardly unique to Lotus).
I’m very passionate about the British motor industry, and Lotus in particular, so I still think it’s a pity that a factory backed solution isn’t on the table..
.. which is an ironic opinion from someone who has recently bought a tired GT3 which blows 111db static. So the aftermarket has its place after all :-)
It's actually something which annoys me about the sports/performance car industry in general. I can understand people wanting an interesting/nice sounding engine by why this obession with making cars so loud. It doesn't make them sound better, quite the opposite in most cases IMO because the exhaust swamps the other interesting noises the engine makes.
With modern exhaust design it's not as if they need to be loud to generate the power.

I couldn’t agree more. I presume some of the modern (turbo) engines are less interesting from an acoustics perspective.. Hence shouty exhausts for that authentic sporty sound!
I think there is also a degree of promgrammed noise control under certain engine load/conditions, to appease legislation.
I was astonished to see that EVO magazine were driving a Ferrari 360 CS at Bedford a month or so back. One can only presume that sound testing was overlooked that day!
Anyhow I think we’re drifting a little off topic now :-)
Lotus, please add a track complaint exhaust to your options sheet. Regards Matt & Kambites.

Do we *know* its too loud for most UK circuits? Or is it conjecture based on listening to a YouTube promotion video?
Nope, we know. Jay Emm has a Lotus Evora 400 with the current exhaust system used on all supercharged V6 cars and it blows over 110 dB static as tested at Snetterton. The other difficulty is meeting drive-by standards which most tracks have a requirement of either 92 dB or 98 dB driveby.

I don't think that all v6 cars have the Evora 400 exhaust, my 350 sport Exige was tested at 97db at Bedford a few weeks ago.The other difficulty is meeting drive-by standards which most tracks have a requirement of either 92 dB or 98 dB driveby.

Smaller diameter pipes.
Can’t say for the latest model Exiges, though.

Forgive my ignorance,but is it so not viable for the UK tracks to raise their noise limits?They are usually in the middle of nowhere after all!1

Which stands for assholes who buy a house next to a race track, then complain about the noise to the council.
"Therefore, it never ceases to amaze me that some folk will purchase a property within the vicinity of a circuit and then complain about the noise it generates."I am amazed that the councils bend over to these residents,it's like complaining about airport noise.I havent heard a runway in Btitain to be shut down by Nimbys,apparently tracks are considered much more expendable as they are not essential transport hubs.

There was a funny story about people near Heathrow complaining about planes where their flight paths passed over their house. They complained EVERY day via email.

Come daylight savings their complaints came in an hour before the flight passed over their house.
