and here is the y-piece of the half system of Ethos for comparison (see welding and angle):

The Y piece and rear headers look looks very much like a Mercury but I'm not sure about the link and can.

Paul has a full Lazer system that he might be able to compare.

Nice one for the replies guys, much appreciated. Comparing it to the photos of the Ethos system, I don't think they're the same. The Y piece is definately different.

Laser or Mercury? I didn't know they made systems for the NC30.. Laser as in Laser exhauts who make the twin exit exhaust for the CBR600rr?

Here's a few more photos.

And another one...

Laser as in Laser Jama exhaust systems...located overhere at Heinenoord (nearby Rotterdam).

And Mercury as in Mercury Race Exhaust systems....Graham Adkins, but sadly no longer in business with building exhaust systems.

Cheers for the info micpec!
