Hi there!
My name is Rob and I represent Rawtek Performance Fabrication and it's sister company Cortek.
We make the exhausts that are used on the Micra Cup cars.
We are currently getting ready to supply some more exhausts for the 2017 Micra Cup season, and are checking in to see if there is any interest from the public for these kits.
These are premium quality exhaust kits, made from 304 stainless steel, mandrel bent, tig welded and finished with a handmade Cortek muffler. Likely the street version will have slightly more sound absorption, as we won't need to be as worried about the sustained high temperatures, but this will be to the benefit of the user, as it won't be as tinny as the race version.
I don't have much more information at the moment, besides that the retail price will be in the 700-800$ range, although we may be able to put together a group buy deal if there enough people who want it.
Please feel free to message me here or email me rob@rawtekinc.com
