Saw this stage 2 exhaust...very clean, unobtrusive look!

So this was the car I drove by today at Big Sur point. It was going uphill trailing a pack of other cars and I did not notice anything unsuall about exaust note. I thought stage 2 was very loud, no?

I was almost tempted to turn around and catch up with it to take a closer look;-)

Yes, stage 2 is pretty loud. The driver was probably just being very conscious about taking it easy and breaking in the car.

It looks good but you can barely see the Stage 1 exhaust anyway.

I wonder if the diffuser in the vicinity of the exhasut tips gets any soot on it with use. And if this varies with the different setups.

Sound byte please! and why hide those exhaust tips? Is it just really cold where that pic was taken

Yes it is quite loud. I'm willing to bet that ones neighbors would find it obnoxiously loud.

Inside the car, below 6000 rpm, it's loud. With the windows up, it's even louder.

MW and I got to ride in this car. I'm waiting for her to post most of the pictures and comment on our experience. In the meantime, here's the picture everyone wanted MW to take when we all were at the Lotus corral at the Concorso Italiano.

I think the sound of the stock exhaust is nice. How much power is stage II suppose to make and how much does it cost?

I'll leave the hp gain to someone else. I was told the price was ~$700, but I don't think that is the installed price.

~5 hp gain.

 

[James A]

The Lotus quoted power gain is 0.

 

[ivan1]

but it does weigh less...

 

[zvezdah1]

Yep, I'm with Jim, Lotus said 0 hp gain for the st2, but it is lighter.

I could've sworn that at Barber the Lotus folks stated that the stage 1 was a couple pounds lighter w/ no hp gain but stage 2 was significant weight savings w/ 3-4 hp. Has that claim changed now or am I just wrong?

I had thought so too, but I went back and found this thread and it seems HP gains were never reported for sure

i cant believe a decent exhaust with as few bends as possible cant make any more horsepower than the stocker...
it certainly will be interesting to see what happens when this car starts getting some parts made by GOOD tuners...
how can they sell an exhaust for 7-800 bucks and not have any increase in power?? dont just say "cause its lighter," ..IT SHOULD BE LIGHTER ANYWAY!!!

stage 2

The weight loss is 5 kg / 10 pound us .

But assuming that the stock exhaust was well designed, why would a different cat-back only with no corresponding intake mods be expected to change much?

 

[evomind]

because the manufacturer has to meet meet certain federal regs that after market does not...
granted, most gains will come from the headers or exhaust manifold.....
just 800 bucks is a lot of money for an exhaust where the only performance gain is 10 less pounds....
ive just never seen a good exhaust system NOT give performance gains...of course im used to either v-8's or turbo cars...
also, i understand it will be very hard to extract much more power from this motor being a small 4 banger non turbo engine...
to see any gains might have to take the cat out and let the exhaust breathe better through better headers or something

Man, what a horrible cutting job.
