Used 1.7/1.8 exhaust extractor. Probably Thunderbird. I haven’t done anything with it so it’s dirty and lots of surface rust but all the pipes are solid, muffler has some dents and looks like it may have been leaking. Three bolt muffler flange. $75 plus actual shipping from 38363. Or pick up in Parsons or Cleveland TN. You can estimate shipping on a 25 lb box 48”x13”x10”, I’ll pack it securely in the smallest box I can fit it in, and charge what it cost. I can’t ship until the 16th. Check, cash, money order, or PayPal friends and family. 1.7/1.8 Extractor Exhaust video
