This is our original down pipe designed to eliminate the restrictive converter inlet pipe found on 97-04 Grand Prix and GTP, 00-03 Monte Carlo, 00-02 Impala, 97-03 Regal and 98-99 Intrigue. Installation of this pipe will require it to be welded to your original converter.
This is a simple bolt on pipe without converter that is for off-road use only and bolts directly to the exhaust manifold and to your factory resonator pipe or aftermarket Cat Back. This pipe allows the largest performance gains of all our down pipes for the 97-04 Grand Prix, 00-03 Monte Carlo, 00-02 Impala, 97-03 Regal and 98-99 Intrigue . This pipe is a true bolt on, which can be performed with simple hand tools. Note: Off road use only.

This is a direct bolt on replacement converter assembly, with hi flow catalytic converter for 97-04 Grand Prix, 00-03 Monte Carlo, 00-02 Impala, 97-03 Regal and 98-99 Intrigue. (Note: Some 2000 and up models have problems with SES lights, to combat this issue we have introduced a new DP4 with a improved design converter. If you don't want to take a chance, simply order the DP4.)
