Quick Links: Here are your required Tuning options Description Increase the performance and reliability of your BMW X5 35d M57 by eliminating the restrictive Diesel Particulate Filter (DPF) and Selective Catalytic Reduction (SCR) system, thus allowing the exhaust to flow more freely. This DPF/SCR Delete kit is built to last with 304 grade stainless steel and the world's most reliable aftermarket flex pipe. Rawtek has engineered this kit to be as good as it can be. From the precision machined turbo flange to the large 3.5" OD constant diameter tubing that ends in a concentric reducer to bring it down to 3" OD, nothing will outflow this downpipe. The SCR delete midpipe is made from 304ss 16 gauge tube. It is fully tig welded and includes hangers in the stock locations and an optional high flow Diesel Oxidation Catalyst (DOC) from GESi, for those who want to cut down on the extra diesel smell. For bulletproof reliability in even the most severe environments and to help reduce under hood temperatures and noise, we build these downpipes twice as thick as anything else on the market. Yet another reason we can offer a lifetime warranty that we’re confident you’ll never have to use. Installation time Installation time will vary greatly based on experience, know-how and having the right tools and lift, so please take the following prediction with a grain of salt. This is simply a general idea of how long it could take in an ideal situation: Around 10-12 hours. Benefits:  ***When combined with required software*** Up to 342 whp** Up to 504 wtq**  Longer turbo life (no more DPF) Features: 304 stainless steel 3.5" OD 11 gauge tubing (for the downpipe) 3" OD 16 gauge tubing (for the midpipe) Optional DOC from GESi Stainless steel installation hardware included EGR lower end cooler off the turbo is blocked off EGR intake is deleted through the tune No transmission reprogramming required Fitment: Will fit the following North American spec vehicles with DPF (diesel particulate filter): BMW X5 35d (2009-2013) **Certain models of X5 have no factory connection by the rear axle, for these models you simply need to make 1 straight cut and use the provided band clamp** ** Power levels reflect the Malone stage 2 tuning software reported numbers. Much more power can be made with higher level tunes and supporting hardware upgrades. As with all aftermarket tuning, the condition of the engine will factor into power levels generated
