    No Box?
    Part is fine but not sure if it was dented when shipped or got dented on the way to us. But it wasn't in a box so it was dented. Got 2 parts both not in box and both dented.

    Exact Fit, Runs Great!
    Tried another brand and it was very poorly made and would not fit. Ordered this unit and it bolted right up and fit perfectly.

    Great Replacement
    I replaced the OEM header/cat about three months ago. It resolved the 'check engine' light I had. More importantly, I haven't seen a decrease in power or fuel efficiency at all. This was a concern initially because the design of the Walker header doesn't appear to allow exhaust gases to move as smoothly. Great product overall.

    Part
    The part is used, not new. The price is too much for used part.
