Walker 51033 Pipe Seems to Be Incorrectly Designed


The application is a US market, federal emissions, 1996 Honda Accord LX sedan with the four cylinder, 2.2 liter, F22B2 engine. The holes in the converter-facing flange of the Walker 51033 pipe are too big, roughly the same size as those in the mating flange of the Walker 16067 catalytic converter. The non-threaded portion of the bolt in Walker kit 35129 passes through both flanges. It should pass through the converter flange, but only the threaded portion should pass through the pipe flange. The competing Bosal 713-359 pipe appears to be correctly designed. Pictures can be seen here: https://photos.app.goo.gl/srjADPYzxLEyWxGY8.
