Previous owner installed dual straight 2.5 " pipes on mine w glasspaks....not loud and very close to body , no dragging any mufflers...and at the tail I installed the dual chrome tail pipe extensions from early 70`s t/a ...bought at EBay for $100... some people say they hate glasspaks , but these are not loud , just a good V8 rumble...you cannot hear mine next to some other birds..
