Quite a few of us vintage spider owners run the "Ansa" twin chrome tip muffler in place of the stock rear muffler...it adds a bit of a nice low tone with out being too loud...some of us make other mods to our exaust for performance and letting our motors breathe better..
Depending on the state you live in its best to make sure of any changes you make won't disqualify you if you have to be inspected as a licensing requirement ,
I'm in a state that doesn't inspect anymore
