Quicksilver's Elise Exhaust has arrived. It's official weight, measured on our FedEx scale, is 14.6 lbs. That's more than 10 lbs lighter than stock and 3 less than the Stage 2. We plan to have dyno results sometime next week. No diffuser mods needed. On sale now $649.99 (reg $699.99)

10# lighter than stock is music to my ears. I look forward to seeing some dyno numbers.

Nice looking unit.
99db at full chat.
Is this for a new unit?
How far away was the sound meter?
what was the orientation of the sound pick up to the exhaust tips?
I'm concerned as to what it will be with 2-3 yrs and 17k miles on it.
My local track has a limit of 102 from a fixed station 35 feet distant and 15 degree offset from rear perpendicular.

Like the way your exhaust pipes stays parallel to the street. Not a big fan of the way the Stage 2 points towards the ground.

Will be waiting anxiously for the dyno report. Don't expect any big number difference, just not looking for a loss. (that's some crazy looking bends)

Hard to get more than 1-3 Hp (if that) out of an exhaust. Don't care what the manufactures say.

They tested it with a new unit. I don't have the details of the sound measurement. They measured the stock system using the same test method.

I don't think you need to worry about the local track limit as it is measured from quite a long distance away. There is no way this system will exceed 102 dbs with that test method.

Agreed. Many modern OEM systems are pretty well designed. The improved sound of aftermarket systems is really the biggest feature along with the weight savings.

Looks good, gotta see the dyno. Another question is which design is better for the diffuser airflow. Stage II or Quick Silver?

I don't think either have an advantage since both interupt ideal airflow management. But then again, how often are you driving over 100 mph? The key reason Lotus put the exhaust through the diffuser was to differentiate it cosmetically from the 111S. It was not because of functional superiority. Anyone remember what the original Stage 2 looked like?..:huh:

The better aerodynamic solution is found on the 111S. We'll eventually have a similar solution. ;)

Randy has volunteered to get his car dynoed with the Quicksilver vs. Stock. Hopefully we'll get it done next week.

Please don't tease. I hope this is true. I'm very interested in this solution! When do you think it will be available?

A better question would be how often do you get to 145 mph. 100 mph happens WAAAYYYY TOOOOO easy in an Elise. If you allow yourself any spirited driving you'll hit the high cam... From that point on the needle soon crosses the 100 mph mark. Ask Randy how often he hits the 100 mph mark.

Sorry that was not really fair of me to tease like that! :D We don't have a firm timeframe yet. Probably 2Q05.

You're right the car seems to accelerate quickly to triple digits. With ground effects on cars, sustained speeds over 100 mph are where you can realize some significant benefit or loss. This is how the previous Exige was quicker than a comparable Elise on high speed tracks.

NICE! Will it be dual exhaust just like the s111 or a single like the jansport. I just wonder how much weight will be added due to the added plumbing.
