Frequently Asked Questions

Q: Why should I replace the springs along with the gasket?
A: Exhaust springs lose their tension over time due to heat cycles and vibration. Replacing them ensures the gasket remains compressed and the seal stays airtight.

Q: Does this kit fit both the stock exhaust and aftermarket headers?
A: Yes, this kit is designed to meet OEM specifications and will work with stock headers as well as most FMF or Pro Circuit systems that utilize the factory gasket size.

Q: Is this gasket made of copper or a composite material?
A: Moose uses high-quality composite or crush-style materials (depending on the specific application) to ensure a superior seal compared to worn-out stock units.
