1990-1995 ZR1 CORVETTE HEADER AND EXHAUST SYSTEM
INSTALLATION INSTRUCTIONS
Thanks for purchasing Stainless Works Muscleflow Headers for your 1990-1995
Corvette ZR1. We have gone to great pains to make sure that our exhaust systems fit and
sound great. Please follow these steps to ensure that your installation goes as planned. It
is recommended to use a lift for this installation, or as a minimum jack stands on a level
surface.
1. Disconnect the battery.
2. Remove center wheelhouse sections for easier access to manifolds and headers. It
may be necessary to remove rear wheelhouse on right side.
3. Remove air pump valve assembly under brake master cylinder area and lay on top
of ECM.
4. Remove heat shielding from right and left manifolds.
5. Remove air tubes from manifolds. Both right and left sides.
6. Remove oil dipstick tube.
7. At this time remove all manifold bolts accessible from top.
8. Raise vehicle.
9. If replacing old exhaust with Stainless Works 3” system, remove old system by
loosening clamps and 3 bolt flange at converters. Remove bolts holding hangers
and remove exhaust.
10. Remove EGR tube from the right manifold. Be careful in disconnecting the EGR
tube and saving the v-clamp, to be used when connecting to the header. Only ’93
– ’95 cars have this EGR.
11. Remove remainder of manifold bolts, disconnect O2 wires and remove manifolds.
