This converter was originally promised by AutoAnything in four days, but it took closr to twenty days, This delay was horrible to explain to my customer. The weld at the entrance flange was not in line for direct flow. A portion of the pipe stuck into the entrance thus impeading a smooth flow to exhaust gases. This could have been corrected by our shop, but it would have voided the warranty. The material quality and price seemed reasonable, but I'd only order another one with reservation.
