Titan Motorcycle Co. of America Exhaust Port Gasket Evo/ Big Twin

Sold in 2-packs. 

This is the flat "Race Style" exhaust port gasket.

It is made of a knitted stainless steel wire mesh, which is compressed to a 1/8" thick gasket that is flat on both sides. (In other words, it is not the tapered style.)  It has added carbon/graphite for strength and fill.

This gasket is approximately 1-5/8" ID (41mm Inside Diameter) by 1-15/16" OD (49mm Outside Diameter), not to be confused with the "interconnect" or "crossover" gasket that is much smaller.
