Lightest Exhaust

Hello community,

What is the lightest exhaust on the market for the Toyota engined Elises/Exiges?

So far I know of Arqray Single Tip Titanium
and Quicksilver Titanium.
The latter isn’t entirely made out of Titanium, only the tips afaik.

Does anybody know of any other exhausts?
I very much like the Arqray, but it is too expensive to get it shipped to Europe, with all the duty fees :cry:

Another thing:
Does installing an aftermarket exhaust reduce the poweroutput of the car?

If you are looking for a really light exhaust you will end up with a really loud car, it will be no good for trackdays etc
I went in an Exige S with a 2bular ultra and it was really really loud, the owner wished he never got it.
There have been problems with power loss with aftermarket exhausts and AFAIK the only one developed and tested to show no drop in power is Lotus’s own exige S exhaust. I just had one fitted and I am really happy with it.

Boothy

I have noticed (might be of some use) with exhausts, what is gained in bhp as lost in torque…dont hold me to this…im only going off my past experiance with other high output engines

I’m pretty sure my exhaust is very light and I’m very certain it’s louder than a 2Bular Ultra exhaust (not by very much though). Tracking is a problem though.

If it’s after loudness you’re after - I know of a Lotus dealer in Germany that sells a exhaust with flaps - in other words, when the flaps open, the exhaust is bypassed. IMHO, too loud, too expensive, it’s quite heavy and doesn’t sound the part though…

Actually I am looking for a very light exhaust, that is still track friendly and doesn’t reduce torque or bhp.
I guess you can’t have one without the other…what a shame

2bular GT3? but it still a bit heavy, the other option is to contact Jim from 2bular directly he is a wealth of knowledge and can make pratically whatever you want
he has for me

Having the QuickSilver UL fitted Thursday along with the manifold… Also having the Reverie diffuser fitted and eliminator kit…for extra lightness!

Any idea how much weight you have saved with these installs?

Will let you know at the end of the week

Was all standard back there on my car manifold, exhaust, diffuser weighing in at 31.2kg. The total weight of the Quicksilver manifold, ultra light titanium exhaust, eliminator kit and carbon diffuser is 15.3kg. The big saving is in the manifold and especially the exhaust, the one that came off was HUGE! I will say they both look the nuts, real quality. The eliminator kit will surely help the cooling and the diffuser looks excellent but there was hardly any difference in weight! I’m sure an old hand like Mr P could of told me that

Is there still problems with the Lotus Stage 2 Exhaust For the Exige S
I think somebody posted that the wels still fail ??
Is there actually any Power gain from these systems ? over the stock

no power gain

my welds fail all the time

but still worth it!
