Treadstone 1.75" Stainless Steel Flex Coupler




Product Description

1.75" S.S. Flex Coupler. Flex couplers are used to isolate engine vibration to your exhaust components, and prevent cracks in your downpipes, cat-backs headers and turbo manifolds. We have introduces a high flow flex coupler with stainless steel interlocking lining to help increased exhaust flow through the coupler, and prevent excessive back pressure to build up. Standard flex couplers either have a braided inner liner that in time will burn out creating an obstruction in the exhaust track, or others with a flex bellow that creates turbulence when exhaust gases flow through. These are the only type of flex coupler that can withstand high pre-turbo exhaust temperatures. Meaning you can use these couplers when complex turbo header designs are needed to prevent turbo header cracks. Perfect for turbo downpipes! We use these in our WRX turbo kit up pipe!
