This is a pair of NOS WALKER headpipes(exhaust pipes if you prefer) to fit the following Buick models:1960 LeSabre series 4400 and Invicta 4600 series with dual exhaust. They are Walker part#'s 4334-8 RH and 4335-9 LH. I didn't realize I had these because Walker consolidated their pipes and changed to a 5 digit numbering system in the late 1960's and lumped all the 1960 models to the same part number as the Electra's. This is the specific ones for the vehicles listed(LeSabre series 4400 and Invicta 4600 series) and they were in 2 different buildings! These pipes are original cold rolled steel and were discontinued in the mid 1960's! Hard pair to find! The 8 foot pipe has a little more rust than the 9 footer but these are heavy, thick walled steel and are the correct Buick "ball and socket" flanges at both ends! Please note that these are 8 and 9 foot long pipes and I CANNOT ship them before you even ask lol! I still have over 300 NOS Walker exhaust components and will post interesting items from time to time or inquire if you have other needs. Most of the muscle car stuff is long gone and my stock is from the 40's to 1975. I have no parts for cars 1980 and newer. Call for apt to inspect or purchase this set and it is all I have left for these models. Thanx
