Anyone eared of FRAMAX!
On my search for an exhaust system just found this Brazilian 2-1 system.
They also seem to have branched to Portugal just 30 Km from my home! so will be paying them a visit soonish, as the site does not offer much information.

PS:
The pipes do look smaller in diameter than the "usual" systems...


A few more informations:
The silencer cans(all in inox 304) work with a "reflexiv camera system" so they dont have/need ceramic coating or any isolation foan.
You will probably need to adjust fuelling mix.
