Broken Corsa baffle symptoms?
I know Corsa mufflers were known to fall apart internally. Before I consider spending money on quieting the exhaust, I want to be sure that mine is still sturdy (last year at the inspection station I heard metallic noise that sounded like it was coming from the muffler, but it could have been something in the shop: I haven't been able to replicate the sound).
What symptoms or things can I do to check if it's junk?
