The Ace Race Parts brand of 3-Bolt Exhaust Flanges is precision-cut from CP2 Titanium. Each flange features chamfered edges, round bolt holes, and an overall thickness of 8mm (5/16"). These flanges are directly compatible with our 304 Stainless 3-Bolt Flanges and 3-Bolt Exhaust Flange Gaskets, making them an excellent choice for transitioning from Titanium to Stainless in existing bolted exhaust applications.
