C5 Corvette Z06 American Racing Headers 2" Long Tube Header System (2001–2004)

The American Racing Headers 2" Long Tube Header System for the 2001–2004 C5 Corvette Z06 replaces the restrictive factory exhaust manifolds and mid-section with a complete long tube header and X-pipe configuration designed specifically for the LS6-powered Z06. The system runs from the cylinder heads to the rear axle connection point, where it mates to your factory or aftermarket axle-back exhaust.

Large 2" primary tubes, 3" merge collectors, and a 3" X-pipe mid-section increase exhaust flow and help the LS6 engine evacuate exhaust gases more efficiently at higher RPM. This configuration is commonly chosen for aggressive naturally aspirated builds or combinations targeting maximum airflow.

Catted vs Catless Options

2001–2003 — With Cats: C5-01200300LSWC | Without Cats: C5-01200300LSNC
2004 — With Cats: C5-04200300LSWC | Without Cats: C5-04200300LSNC
