Datsun Roadster 1600 Header Flex Pipe IN STOCK AFTER MARKET USA
1600 flex pipe. Click here, to view the gasket that goes with this part.
Stainless braided area of the pipe measures 2 inches O.D. The I.D. of exist port of the pipe is 1 3/4 inches. Overall length is 9 inches. This diameter is slightly smaller than our 2000 version, but has sufficient flow for the 1600.
Our flex pipe, pictured on the blue back round, has a longer flex area to allow motor movement without pulling on the exhaust. The longer area also acts to dampen the exhaust pulse away from the exhaust system that can be hard on welds.
Compare our flex pipe on the blue back round, to other generic (short) flex pipe on the white back round, which is similar to what other vendors are selling (see photo) which has reduced flex length, too rigid with a small diameter inlet.
