Wayne Walker Posted September 27, 2015 Report Share Posted September 27, 2015 We will be allowing any Modified type header as long as they meet what was posted in August. NO tri-y, merge collectors, or 180s. ALL CARS MUST HAVE MUFFLERS AND SCATTERSHIELDS. NO EXCEPTIONS http://www.lonestarspeedzone.com/topic/67481-cbs-show-down/ Link to comment Share on other sites More sharing options...
