I'm thinking about getting one - have heard it in garage, but wondered if it will be annoying during day-to-day use?

Sounds good at high revs, but will it bug me when using it every day, sadly sometimes spent cruising on motorway etc..?

Cheers

haven't done a long journey yet so can't say with any authority. AM going to cotswolds next weekend so will let you know. It's certainly not a headach inducing drone round town, it's not that loud, just a bit more purposeful than standard.

Thanks S7 EXG - believe we are in two way chat via Al on this and other topics

Footsoldier - I spent 1 1/2hr in car on return from factory (motorway and back lanes to end) and found the background noise from my son to be more annoying that the exhaust note

I had one fitted last week, and very happy with it. I think the engine has a good, tuned note to it anyway, and the exhaust helps you hear it! It should have been standard of course...

I fitted a Milltek exhaust to my old Europa and then took it off, because it was too obtrusive as it popped and banged everywhere. This is much better and I'd recommend it for those with no patience to wait for aftermarket alternatives (eg me!)

Hi chaps had my car fitted with sports exhauts from blue flame, it looks and sounds great, they told me the evora has 3 cats two with sensors and one without ,the one without has now gone and the new exhaust is a much better design flowing in from the middle of the silencer instead of the left hand side easing up the flow, I have to admit the car does feel quicker.

I got my Stage II sport exhaust yesterday. It sounds and feels great when you are on the throttle and is almost as quiet as the standard exhaust when just cruising. One way to quantify the extra power is to note the increased fuel economy. I'm getting just about 2 mpg better mileage for similar driving. Of course you may lose that if the better sound on throttle ...

Are people finding the Sports Exhaust 'Sporty' enough after having the car for a few months?

[Mykadams 0]

For a "sporty" exhaust, you have to talk with Komotec (Hangar 111?) or PB Racing...

The PB Racing's one will be mine as soon as I recieve my car. It's a full exhaust system from the mainfolds.

We have a launch edition Evora here, we're using it to develop our complete exhaust.

By now we've tested it on the dyno with the stock and with the stage 2 lotus performance exhaust.

Results weren't bad, i'll post the graphs as soon as possibile, with the exhaust it runs 274 hp, with the stage 2 around 280.

We're planning to make 3-1 manifolds, may step-headers, metallic kat and the rest of exhaust, hopefully to relase some good V6 sound and get close to 300hp.

I'll keep you updated on this!

[Justin182 10]

Interesting! ^

Sorry can't edit the post...let me explain a few points.

274 hp it's with the stock exhaust.

The stage 2 lotus performance one is a catback, , its main advantage is in the weight saving.

The "titanium" tips aren't titanium at all, it a thermic/chimical procedure that give it the blu/violet-ish hue.

This is the stock engine, the manifold isn't the best at all:

The kat is close to the engine as in many new engines that need to comply with euro5 regulations. This solution brings the kat at operative temperature very fast, but it's not the best for performance and heat dissipation of the engine bay.

The evora presents a "chimney" over the rear manifold with an exit on top of the car, where there's negative pressure and it can "suck" out the heat.

Here's an example of a manifold for a car with small longitudinal space.

Just to clarify - Lotus don't claim their aftermarket Sports Exhaust that you refer to, has titanium tips. The Titanium tips that are part of the Sports Pack (production fit) are actually Titanium though, the standard ones being stainless steel.

Some updates. The manifold setup has been decided. It has much longer primary tubes! There will be only one kat, a 100 cpsi HJS, and the lambda wires will be lenghtened to reach the metallic kat.

We've decided to use two sliding pipes to keep the two main pipe seperated and garantee longitudinal engine movement freedom, to merge them after that and then use a spherical link to permit flex and torsional movement.

It's a design for independence, very different from the stock one, which has short primary tubes to make the first kats to reach high temperatures as soon as possible.

The rear exhaust is very similar to the lotus stage II exhaust, as you can see in the pictures. I'll have some better pictures of the manifold and of the complete exhaust soon.

299,9 hp, no warning lights.

It's the prototype, so some details may change, but it's pretty much done.

What do you think?

[Justin182 10]

Looks nice. Videos? Price?

[marvin 0]

Nice. How do I get me one?

[RJB 19]

I'm in - when will they be available?

[Gardus 0]

I can't talk about commercial info (yet, we're planning to become advertiser on TLF), you can ask directly to our sales department, look on the official website.

[RJB 19]

Thanks - very interesting, as is the Komotec EV 300 package - very tempted....

Quicksilver have also introduced an evora exhaust into their range of exhausts.

http://www.quicksilverexhausts.com/productbulletin.asp?NewsID=328..

Approx £750inc vat.+ fitting.

We fit them to Aston martins.. Sound very deep but not raspy.

[Bibs 3,621]

^ That will be available via the TLF shop shortly, we're just awaiting the final details.

[Gardus 0]

I've never seen the komotec headers, only the rendering on their website, did they actually build them?
