I had a QuickSilver on my 111R SR that I bought from CN.
It was absolutely superb and if I was to buy another exhaust I would buy one of those.

Oui, il fournit une grande qualite chaque fois que vous soulevez et il pèse cinq kilos moins que "regular".
J'ai acheté un il ya 3 semaines, et voila, il est parfait. Il semble bon et de sons super quand vous mettez le moteur < 3000 rpm!!
Je le recommande!!

Lotus Exige Sports Exhaust – August 2008 – Michael – USA
I have a Quicksilver and I like it very much.
Before installation, I was concerned about the noise, would it be intrusive?
At low speed cruising there is a pleasant burble in the background and obviously, upon acceleration it gets louder, which is perfect for me.
At highway speed, it was not intrusive.
I recently heard a Stage 2, and noticed that it was intrusively loud all the time, too much for me.
The beauty of the Quicksilver is that the noise level only increases when you want it too.
Hope this helps.
Michael

Lotus Exige S Sports Exhaust – August 2008 – TS – USA
The Quicksilver is great exhaust!
It is loud, but it is a sweet sounding type of loud…
The build quality is nice and they don't fall apart from bad welds.
It also has a deeper tone than the Larini which to my ear sounds more like a performance exhaust on a large bore performance bike compared to the lower tone of the Quicksilver.
You will love the QuickSilver if you decide on it.

Not ‘chavvy’, but gives a bit more burble.

Lotus Elise S1 Sports Exhaust – August 2008 – Rich – UK
I have one (QuickSilver) fitted to my S1 111s.
Replaced a Janspeed. I prefer the Quicksilver.
Power comparable, noise "warmer" than the "metallic" Janspeed.

My Quicksilver sounds ace especially over 5000rpm where the Lotus stage2 for the Exige S is louder

Lotus Elise 111R Sports Exhaust – August 2008 – R - London
I fitted the standard Quicksilver (not the titanium jobby unfortunately!) and I have to say I absolutely love it.
.. relatively straight forward to fit and certainly I would happily offer advice on that.
I changed because I couldn't get onto a lot of tracks with the Stage 2 but didn't want to loose the drama that a sports exhaust adds over the standard.
I am loving the QuickSilver I have to say.
The build is excellent, being even lighter than the stage 2 and extremely light next to the standard fitment cattle trough that Lotus fit.
The sound is awesome with lots of gurgles, pops and the odd bang.
On second cam it is fantastic but when driving sensibly, it is very civilised compared to the Stage 2.
I can't recommend it enough however I must add that I haven't experienced any other makes.
Looks wise the oversized pipes look great coming out of the diffuser.

Hi Paul
The system is great, first track day was brilliant!
Again, sounded great I’m really happy with it.
If it’s of interest I’m fettling the diffuser and exhaust brackets on the car to enable me to quick change (5 minute) the exhaust!
Best regards

Hello again ,,,
I wanted to email you to telll you how satisfied I am with the Quicksilver cat back exhaust system for my 90 Esprit SE .
It is more than I hoped for in regards to construction and sound.
My throttle response seems quicker and the engine is just running better over all.
Cheers

Lotus Exige 2 Manifold, Race Cat & ‘Titanium’ Sports Exhaust – April 2007 – Rob – Australia
QuickSilver Manifold – Sports Cat – ‘Titanium’ System
Peter,
I am extremely happy with the system now. I am even happier about the fact there was no cutting involved to complete the modifications, hence it has retained its functional and visual integrity.
With regards to performance, I have noted the following:
1/ A clear improvement in throttle response. The engine seems to climb through the rev range much quicker. Having said this, there is a significant amount of "popping" on deceleration, and the acceleration tone should be crisper
2/ A significantly lighter car, and I believe I can note the difference whilst driving, as these sorts of cars feel differences in weight much more so than other performance vehicles, due to their light weight and relatively low torque engines.
3/ A fantastic engine note, particularly when the VVT activates at 6,200RPM, albeit a little loud. Having said this, there are many vehicles on the road in Australia, such as Subaru WRXs, Mitsubishi Evos, with much louder systems, hence I do not believe this will cause any issues from a legal perspective. This should provide your business with the confidence to further market your systems in Australia.
4/ Visual impact. You will note from the photo of the rear of the vehicle, the system is now far more exposed due to the elimination of the heat shield on either side of the number plate fixing plate (I actually removed this myself whilst the spacers were being made for the exhaust mount brackets on Saturday). The excellent finish of the Quicksilver system is clearly evident, and matches the overall aesthetic / exposed mechanical nature of the car (as the engine is also quite exposed due to the gauze cover on the rear bonnet). The car really does look very impressive now.
In closing, I could not be happier with your system
I will email you the video files of the static and drive by acoustics, including additional vehicle photographs early next week, as this is most likely the first opportunity I will get to take this footage and photos.
Thankyou for your co-operation Peter. I would now be pleased to recommend your system to fellow Exige owners in Australia

Lotus Elise ‘Titanium’ Sports Exhaust system – February 2007 – TT - USA
Yesterday, I installed the Titanium QS. Install went relatively smoothly. I decided the silver exhaust shielding looked horrible through the rear left grill, so I took the whole rear license valence off, and as part of QS install, painted out the silver exhaust insulation high temp black. Much, much better. Frankly, getting that bad boy off and back on was the worst part of the exercise. The weight of the stock unit was 24.8 lbs, less than noted in other places, but I had popped the weld off the clamp so that might move it over 25 lbs if it had been on the OEM exhaust. I found the Ti exhaust to be beautiful, and the welds on mine were not much worse that what I saw on the Stage 2 Lotus at the dealer. QS Ti exhaust weighed 11.4 lbs, savings of approx. 14 lbs. The Ti QS exits similarly to the Stage 2, just below diffuser. It was really easy to get the Ti QS centered perfectly to come out stock holes in diffuser. I got it first time, without even a “trial” fit with diffuser. How? I measured from the lowest body point left and right (where the two perpendicular diffuser screws attach) to the center of the tips – moved the exhaust back and forth till they were exactly equal both sides. When I put the diffuser back on, the pipes were PERFECTLY centered. I did note that the place where the pipe comes out of the exhaust can (right end looking from rear), at the point just after the pipes turns 180 degrees and heads back left (towards exhaust tips) was fairly close the alumimun shielding. I was able to install exhaust without touching, but I had to rotate the exhaust slightly forward to get it to have the most space
Okay, sound. First, let me say that I am in break in so I have not comments about sound “on the cam”. I did note right off that idle sound is louder and deeper. It has a slight burble too, even at idle. It is not offensive but definitely louder. It actually seems that the loudness is highest at 3000 – 4000 rpm and with resonance to the extent there is any, more around 3000 vs. 4000. On the throttle, it is definitely louder and meaner sounding than stock from idle to 4000 but above that it almost seems to level off. I put it in 5th and cruised at 55 to 60 and had NO resonance at even throttle. When I opened it up from there, it was loud but actually really wonderful sounding. Probably most fun is when you shift, its pops beautifully in between most shifts. The popping and burbling is deep and sounds like the car should sound. I did notice I almost seem to get the most resonance (droning) when I left OFF the gas from 4500 or so on down. That is okay with me. It is early, I haven’t gotten it up in the RPM range, but I am in love with this exhaust. If you light foot it on accelerating, you can keep the tone down. If you want the noise, just nail it. And in between, the pops and burbles sound incredibly cool and appropriate. And 14 lbs less weight, and frankly the exit just below the diffuser are really good by me. I will see if I can get a recording once I get through break in.
I recognize this sounds stupid, but it seems like I could feel a performance difference (supposed to be dyno’ed for 6 HP) but its probably my imagination
It is the lightest of all the "through the diffuser" aftermarket exhausts. EVERY ONE loves the sound of it. On the second cam, it is positively outrageous. Its expensive but if money isn't your primary concern, I'd recommend it. Quality was/is good. Some people have reported welds that did not look really pretty. Mine was absolutely good quality.

Lotus Elise 111R Performance Muffler – February 2007 – Jim - USA
I love the sound!
It's pretty loud and gets slightly louder with time.
It has a nice mellow tone at idle and screams at WOT.
Lots of pops and burbles when the throttle is abruptly lifted
BTW, I get as many comments on the sound of my car as the looks.

Lotus Elise 111R Performance Muffler – October 2006 – S - USA
I had a QS exhaust on my first Elise for 20,000 miles, no rub, no need to cut anything, and it sounded awesome.
…my exhausts were obtained from Sector111 - the best!
______________
Lotus Elise 111R Sports Muffler – October 2006 – E - USA
Have had a QuickSilver on my Elise for five of its six thousand miles and I really like it.
In my opinion it's just loud enough and produces a deep quality sound. It also has a great sound when up on the cams.
There was no need for me to trim anything when I installed it.
It was worth the $$$.

Lotus Exige 2 ‘Titanium System’ Racing Exhaust – March 2006 – Greg – UK
“Amazing sound which brings the car alive and makes it feel like there’s a lot more ‘oomph’. Sounds even better when the car is cold.
Couldn't believe the weight compare to claimed ‘lightweight’ Lotus Stg 2 system.
It's louder than previous Stage 2 Lotus exhaust, up to the Cam switch at which point it becomes much quieter.
Above point may make it a bit tiresome on longer journeys, but not yet sure as haven't done any!
It looks great.
The transition between low and high power bands (i.e. the cam switch point) appears smoother - which suggests to me there may be some mid range torque improvements”
:O)

Lotus Elise Ser 1 Sports Exhaust – September 2005 – Rob - UK
Hi Peter/Paul
Just thought you'd like a quick update from this season.
You'll be happy to know that the exhaust handles 200+bhp with no problems at all.
I know the engine I purchased for this season was last dynoed at 190bhp, when it was installed in my car with different throttle bodies it produced around 12bhp more with good torque right through the rev range so very happy with that.
Plus the added bonus that the max dB didn't exceed 100 all year even with a CRP fitted.
Kind regards
Rob Clarke

Lotus Elise 111R Sports Exhaust – July 2005 – John - UK
Paul,
Thanks for this.
The system on my car I like. It's reasonably refined in steady state cruising mode which was my main concern, but on the other hand make the right noises when you want, and there is a glorious burble on the overrun, which keeps me wanting to change down a gear and listen! Interestingly, and I'm not sure why this should be, it's also drastically changed the note that I get from the ITG at the cam change point. Previously got a very distinct "bark' at 6200, which now has been softened. As I say, can't understand this, but it's not really a problem.
Have to say it looks good as well, although I hope you don't go down the upswept tail pipe route as I would definitely hanker to change as I think it would look so much better, and would also differentiate it from the (current) competition!
All the best
John.
PS Also meant to say that the throttle response seems better. Guess as the ECU re-programmes itself things can only get better as well.

Lotus Elise Ser 1 Sports Exhaust – November 2004 – Rob - UK
Peter/Paul
Firstly, love the exhaust!
The cars throttle response is much improved over my old JanSpeed Supersports. Bottom end pickup is a lot cleaner and seems to have more torque.
Top end is as improved as the bottom with the car revving around to 7500rpm with hesitation - top job!!!
Just got back from having my car on the rolling road and thought you'd be interested in the results.
To say I am very impressed would be an understatement!
Basically the car hasn't changed since my last rolling road session apart from the addition of the QS exhaust.
Although peak power only increased by 1bhp, this isn't a fair result as my top end is needed a complete rebuilt (winter project) but the bottom/mid range improvement is fantastic.
Makes my old JanSpeed look a bit rubbish
:o)
BHP - Upto a 8bhp increase with an average of 5bhp across the rev range
Torque - Upto 9ft/lbs increase, again with an average of 5ft/lbs across the range, and it has reduced a nasty dip aourn 4000rpm
Dyno plots attached, white line is the new power and red is the old.
Kind regards
Rob
