I have a used Flowmaster 2.5" exhaust system for 68-72 G.M. A-body. Includes Dynomax mufflers that are only a year old. Also has the extra tailpipe end piece that are cut on a angle instead of the turn down style that is on it now. Has 3" cheap collectors reducers on it. Kit was bolted together so you should be able to modify the fit. I smashed the crossover pipe with a hammer to clear the driveshaft. What you see is what you get. I'm not shipping it, pick up only. Located in Chicago IL. $200 obo. 773-677-0129
