My 44 mm tial dumps straight to the ground right between the oil filter and downpipe, love the sound! Doesn't even sound like an exhaust leak, more like a mean screamin eagle when under full boost. Internal wastegates with o2 dumps sound like a huge exhaust leak, the way my 16g car was. Tials sound more proper and aggressive when dumping. I like dumping. Emmissions and power don't go together

Blazing through a tunnel with the wastgate dumping has got to be the coolest sound ever
