I've had three Casa standard exhausts over the last couple of years and couldn't agree more. Everyone of them was such poor quality that I sent them back for refunds. The U-bends are awful and the welds are very poor quality. One GP/DL/SX150 exhaust had welds so dire that returned it in person to Vittorio for a refund.davla wrote:I bought the Casa exhaust and was not impressed with the poor welding around the tailpipe and generally not great quality imo. I returned it a bought the Tutto exhaust which was more expensive but built to last. I've done a few miles on it so far (not many) and it drives and sounds very good.
Given that it's almost impossible to tell the difference between a NOS Innocenti and a Tutto Lambretta one, they are of exceptional quality and there is only ~15€ price difference, IMHO the choice is easy.
