Built from long lasting ceramic coated mandrel bent 2.25" mild steel, this downpipe (with high-flow cat) connects your stock or stock-style header with any stock or stock-style catback system. Works with stock O2 sensors, no welding required.

Does not work with PPE headers or Apexi N1 catback.

This pipe outflows the stock downpipe and replaces the restrictive stock catalytic converter with a more durable high flow unit. Result: long service life and noticeable power increase without much difference in exhaust note.

Gaskets are included.
