I would like to say that this is a great 5 star product for many reasons. Made absolutely accurate to check Walker's website first so I know I bought the correct item but it just doesn't fit, the finish. The pipe is poorly welded and covered with copious amounts of stickers. The screw holes are 3/8" but the gasket I bought (rechecked on Walker's website first) might be a little under 5/16". Who designed this thing. The screw holes are too big and the gasket holes are too small. The bolt used was a 5/16 inch and the gasket did not fit properly. The pipe is not bent properly so each flange is a poor fit and the flange is much larger than the OEM. Poor welds, fit, finish and bends the job that was to be an outright nightmare.
