Exige S exhaust tuning what is best for SC
Discussion
I've seen some Exige S quistions of what exhaust to buy on the SC car, most of them a bit of topic what its origenal was for, so I open up a new ground for disguis?
Some think a stage 2 will do very nice and some say, no I've heard that that will not be good for a SC powered engine because of the more air goes in and out?
The Standard Exige S 220hp engine has already a special made Exhaust wich I guess is a bit bigger bore pipe? and ofcorse single oval endpipe.
Maybe wait putting the stage 2 Exhaust on this car and wait what Lotus says and will do, and or already have.
Most of us know the Lotus Exige GT3 FIA with around 289ps and also SC maybe that exhasut is best because most will give the S more boost and the GT3 exhaust can handle that, and still be within rules of the tracks? I guess, so they must be good?!
Here a photo maked some bigger to see what exhaust it has.
I also remember on the testday from RED motorsport, that they tested a 300hp Exige(the carbon car) and that car had a exhaust I never saw before(not that I've seen that many) but it looked bigger then a standard! and sure different then the Lotus produkts sofar? so maybe ask Martin?
This is that carbon 300ps car look at the exhaust box...
EMISSIONS
Bespoke Lotus Sport tuned exhaust
system with Motorsport homologated

I have been looking into this for the past couple of months since my car will be in next month for the 280RR 
The important thing is gas flow as it can loose you a lot of performance as the zausts are designed for n/a engines
You need something which can cope with the high gas flow plus the extra heat.
The less bends the gas has to take the better too.
Thats why the GT3 look is a good option as there is more gas flow and less bends and more cooling
Another issue is noise levels the added gas will make an given zaust louder so stage 2 good luck getting on track!

Jim at 2ublar is currently sorting out a sports cat for the SC application as the standard will be restrictive
I have seen a pic and it looks like a beast! and has a 375hp capacity so no probs with the yota output.
Will post findings once the beast is done!

doesent seem to make much difference on an SC car to be honest...as long as its not restrictive...I have a bog standard Janspeed Roadsport...nice and quiet for track...and 300bhp...other cars run very loud/open...still makes the same power.
So unless you are doing it for the noise, theres nothing to be gained to be honest on an SC car if you already have a sports exhaust........

Fair point, I hate the constant noise also, a good fine tuned sound is nice, to loud is, well a bit aso? for your neighbours and on some tracks you can't drive...also for yourself you get your ears bleede
its fun for 5 min(am I getting old? 
) That Janspeed I don't know how that is made? have heard of them, but don't know what they do? but what is also importand is your exhaust manifold, and yours on the Honda is much different I guess...how are those compared to the yota? bigger bore? better curves/flow?
GTRene
yep - manifold is most important...its a custom jobbie for the Honda cars - depending on NA or SC you get 4-1 or 4-2-1
you can buy exhausts like the ones above in the pics with small cylinder and one exit pipe from a few places in the UK ...they are just lighter really
The Janspeed jobbie looks just the same - small cylindrical silencer, but with 2 pipes coming off it - thats it really ...nothing special, but under 98dB so you can get on tracks no problem ....

Today I was in Lelystad Holland their was a slalom day and I saw some nice Lotus there, also some strange made Exhaust..look at this! its a very lightweight only around 4kg!!
But looked musch more see here the result...
here a bit closer...
personaly not my taste, only that low weight 4kg is

bogie said:
yuk ...guess it would be 2Kg with just one can then?
yeah...gues he did get them for: two for the price of one... Also saw a nice looking JPS S2 still with the golden wheels(yours have nice blacks now
) and with a Exige wing with BIG JPS writing on it...see here;
and here that car with wing from aside
and here together with that Elise Bike sorst...
There was also a Honda conversion S1 Elise with a S1 Exige frontclam like yours(bogie) has.
see here...
So all in all it was nice to be there for a while and see some more Lotus.

Ugh, what is it with this wing addition nonsense. Chav my Elise?
it gives you wings
But personaly I would not put such thing on my car that fast...
Only when seriously racing or whe it realy gives some benefits to your car...
But still I like what others do tho their car
gives me some ideas what you can do or what not to do or what is overdone... I also talked to a Lotus Specialist who also build a few 6 or more? Elise Hondas
and I was talking about the possibilities of such car, and he offered me to come by his workshop and try such car out someday, he's getting his engines out the UK and told about tuning stages non SC to 240hp and with SC around 300hp and whats more on such car, interesting talk they where also there with a car who did some slalom runs, and this car was totaly matt black and it looked not bad! also I saw a different light house? but they only had the covers removed cause of damage, and they leaved it that way because you can't buy only the lightcovers?? and a new unit was expensive(they have HID) but also this did not look bad at all
see for yourself: 
cheers
