Super Sic, we are still working on them, we have Mks stock unit that he let us cut up and we have been mocking up test-pipes, its been hard to get this done with the amount of cars coming and preparing 4 race cars for our last race this weekend. Once this race is complete we will be all hands on deck for the test pipes. We promise it will be done
