NOTE: Finish the performance job your headers started by adding a Hooker competition dual exhaust system. Large 2 1/4” diameter tubing is
mandrel bent, not press bent. Mandrel bending maintains a consistent inside diameter form maximum flow; press bending will crush the pipe,
easily reducing volume by more than 10%. Our dual exhaust system is perfect when used in conjunction with Hooker Super Competition Turbo
21105HKR or Hooker Competition Turbo 21005HKR. Purchase duel exhaust no. 16520HKR: 1970-81 Camaro; 1978-81 Firebird; 1968-79
Chevy II Nova. Purchase dual exhaust no. 16500HKR: All other applications for header 2451HKR (16500HKR includes 2 competition turbos).
