Specs At A Glance

Good To Know

Q: Will these fit any 3 inch 3 bolt collector flange? A: They are listed as universal for 3 inch, 3 bolt flanges, but bolt spacing and port shape can vary between brands. Measure your flange before ordering to confirm the match.

Q: Can copper gaskets be reused after removal? A: Copper collector gaskets can sometimes be reheated and reused if they are not crushed or cracked, but replacement is the safer choice for a reliable seal. Inspect the surface before reinstalling.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
