These pipes are available without or with converters. Pipes without converters are for off-road use only; those with converters are for either off-road only OR street use. Flow improves due to mandrel-bent 2.5" tubing & the "Tru-X" that replaces an inefficient factory H-pipe. ''Tru-X'' pipes are constructed from 100 percent stainless steel.

Note: These catalytic converters are no longer legal for sale in the state of California and will not be shipped to the state of California.
