OSIR Exhaust system

We spent 4 years of development, six versions of design refinement and test drive them everyday. Its time to let them out to our customers

We built them with ASPEC under the highest craftsmanship
We smooth out each turn on all the piping and retain the diameter for maximum flow
We tuned them with a deep tasteful note
You can choose between Stainless steel and light weight Titanium that suit your need
