Yes tabs and bolts as of 2014 will NOT be legal. You will either need one of the two excessively priced NHRA approved tether systems or as amended a one inch stich weld on ALL the primary tubes. Results of racers NOT doing maintenance on their cars and causing injury to others.
I have tabs, bolts and mufflers and still have to conform to the new rule.
