3″ Downpipe

This is the infamous SFR true 3″ downpipe for your turbo. One of the main reasons we decided to build this particular pipe was due to the size of the turbos people are using. Some larger turbos have up to 2.75″ outlets on the hotside and the stock downpipe presented a huge restriction.
The stock pipe can be smaller then 2.25″ inside diameter. The SFR downpipe is 2.85″ on the inside! We machined grooves into the flanges to except the factory o-rings for sealing purposes. The SFR 3″ downpipe require two of these crushrings.
