DSM FP30 Downpipe


A downpipe built for FP30 turbos/turbine housing setups looking for increased flow rather than a direct bolt on (We also offer an FP30 O2 housing to bolt directly to a factory style downpipe)

Getting rid of the factory 2-bolt downpipe connection flange means the bend coming off the turbo can be greatly opened up for better post turbine flow. This is set up ends with a flex section/bellow right by the transfer case area (that slips over a 3″ exhaust) to be spliced/welded to your current set up or a great starting point to build off from with all the hard parts done for you. We can end it with a v-band assembly just after the flex bellow if you prefer for an additional cost (shown in photos), but ending with the flex bellow does make it easier for you to slip over and weld to an existing 3″ exhaust.

-FP30 specific one piece downpipe that ends with a flex section/bellow near the back of the oil pan.
-Turbine housing outlet clamp.

-Optional dumptube (+$80) or recirculated (+$200).
-Optional quick release clamp assembly at the outlet (+$70).
