This is an NOS (new old stock), catalytic converter back exhaust system that will fit 1984-1987 Buick Grand National and T-Type vehicles. The mid pipe fits 1984-1985 models only, and the over axle pipes, muffler and tail pipes fit 1984-1987. I purchased this system in 1987 brand new from a GM dealer and never installed it, intead deciding to trade my T-Type in on a brand new 1987 Mustang GT. It has been sitting in my barn since then and still has all of the original stickers, tags and finish intact. If you are looking to replace your old system, especialy those of you looking for a concours restoration, these original items are nearly impossible to find as they have long been discontinued by GM. Here is a list of the part numbers:

25518391 mid pipe

25520012 over axle

25520013 over axle

25520009 muffler

25520010 tail pipe

25520011 tail pipe

There is some very, very minor surface rust on a few of the components, I am sure this will cleanup easily,it has been stored indoors, out of the elements but it is 25 years old. A great find!Free local pickup in north central Massachusetts available, otherwise will ship immediately after payment received by UPS ground at buyer cost.Thanks for looking and best of luck!
