Key benefits and real-world use cases

Designed with multi-layer steel construction, these gaskets align to OEM specifications and resist distortion under heat. When performing a DIY exhaust refresh, you’ll appreciate the straightforward, direct-fit design that simplifies the job and saves time. The included bolts help secure the manifolds with consistent torque, contributing to a cleaner installation experience.

• Direct fit and easy installation—swap out the old units without extensive modification.

• Broad compatibility across LS-series engines (excluding LS7)—works with LS1, LS2, LS3, LS6, LQ4, LQ9, and more, with compatible part numbers.

Compatibility and installation tips

Before purchasing, confirm that your vehicle matches the compatibility notes and part numbers listed by the supplier. While the kit is designed for many LS-series engines, LS7 is excluded.
