• a housing;
• an inlet tube in fluid communication with the housing, the inlet tube configured to receive an exhaust flow into the housing;
• a first baffle positioned within the housing, the first baffle having a curved configuration, wherein a convex side of the first baffle is configured to face the exhaust flow;
• a second baffle positioned within the housing and in relation to the first baffle, the second baffle sized smaller than the first baffle, wherein the first baffle and the second baffle are configured to separate particles from the exhaust flow;
• and
• an outlet tube disposed at least partially within the housing, the outlet tube positioned centrally in relation to the first baffle and the second baffle, the outlet tube having an end in contact with a concave side of the first baffle, wherein the outlet tube includes a plurality of perforations at the end, the perforations configured to receive air separated from the exhaust flow into the outlet tube.
