Flexible Products

The Ace Race Parts brand of Flexible Products includes a wide range of Flex Bellows and Flex Couplings in Stainless Steel and Titanium. Our Flex Bellows are available in 304 Stainless, 321 Stainless, and CP2 Titanium and provide superior vibration dampening and resistance in high pressure and high temperature applications that experience compression and elongation.

Our 304 Stainless and 321 Stainless Flex Bellows, which feature a two-ply bellow and a solid directional inner liner, are recommended for pre-turbo applications, such as turbo manifolds and crossover pipes. CP2 Titanium flex bellows feature a single-ply bellow without the addition of an inner liner.

Our Interlock Liner style Flex Couplings feature 100% 304 Stainless Steel construction, including the end caps, and provide a smooth and uninterrupted flow for high-temperature exhaust gases. Each Interlock Liner style Flex Coupling contains an external braided section, an internal flex bellow, and an interlock-style liner that can withstand the high temperatures of a forced induction exhaust system. Note that flex couplings are not recommended for pre-turbo installation.
