BLOX Racing offers 4-hole, rubber exhaust gaskets as replacements or for custom exhaust system needs.

Each is made using high density, heavy duty rubber. The 4-hole feature allows exhaust piping to height-adjusted which is the perfect solution for lowered vehicles and race cars. Height-adjustment allows for significant ground clearance when large diameter piping is used. The high density rubber greatly reduces piping movement, shaking and vibration which are the main causes of exhaust leaks. With minimal vibration, exhaust donuts and gaskets remain intact and sealed.

Sold individually.
