(2/4/2013)
All cars must be equipped with exhaust collectors, headers, or stacks installed to
direct exhaust out of car body to rear of car, away from driver and fuel tank. No
part of the exhaust system may be routed through the driver’s compartment.
Exhaust collectors/stacks must be securely fastened (i.e., metal connector
straps, bolted, welded, etc.) to prevent loss of collector/stacks during competition.
Effective Jan. 1, 2014, removable multi-piece exhaust collectors/stacks must be
securely fastened with an NHRA accepted header tether, such as Lokar’s
1400009 or 1401009 to prevent loss of collector/stacks during competition.
