FM IIR divorced flow downpipe for NB
3" downpipe for external wastegate setups.
This is what we used on our famed FMIIR kits (no longer available). It's a 3" downpipe that bolts to our cast outlet on the top and our 3" exhaust system (or one you build) on the bottom. Includes a smaller downpipe specifically for an external wastegate, along with the hardware and gaskets necessary to put it all together. This is a married setup, so the wastegate downpipe merges with the turbo downpipe - this is not a deafening dump setup. Does not include the 1.75" V-band clamp to connect the wastegate downpipe to your turbo, nor the turbo side of the V-band clamp. Works with this turbine housing and a Turbosmart Hypergate 45 external wastegate, may or may not work with others.
