aFe's Twisted Steel Street Series Y-Pipes are constructed of 409 Stainless steel mandrel-bent tubing and come equipped with hi-flow (49 state legal or Canada legal) 400 CPSI catalytic convertors. This Y-pipe incorporates 3 in. down pipes from the manifolds to a 3-1/2 in. merge pipe collector that connects directly to the factory location. The merge-collectors mitered design reduces turbulences for better flow and performance over the tradition form collectors. For a hassle-free install, this y-pipe fits to all OE mounting locations and incorporates the OE hanger, flange and O2 sensors.

For maximum performance aFe recommends combining thei y-pipe with our Twisted Steel headers p/n 48-44003.
