409 Stainless Steel $ 289.95

This is our top of the line bolt on performance down pipe and converter assembly. Built with Magnaflow Super Hi Flow converter but otherwise the same as our DP3.  Magnaflow developed this converter to address catalytic converter efficiency codes that set check engine lights on SOME 2000 and later models.  If you want to ensure that false check engine lights do not occur and get the best performance possible with a converter, this is the unit for you! This pipe fits 97-04 Grand Prix and GTP, 00-03 Monte Carlo, 00-02 Impala, 97-03 Regal and 98-99 Intrigue. See our Accessories page for all of your gaskets.
