• SDP 2011-2016 Lml Twin Kit


    SDP Duramax 2011-2015  LML twins- up to 750RWHP


    -Keeps the 2nd battery under the hood.

    -Includes 3" Y-bridge

    -Includes 1gal custom SDP coolant tank WITH low level sensor (raw, polished or powdercoated)

    -Completely TIG welded, makes for very smooth joints and the insides of the tubing are flush. We strive to have the highest quality welds in the industry.

    -Custom higher flowing mouthpiece that is also o-ringed to ensure there are no boost leaks where the mouthpiece mates with the factory turbo.

    -We include a V-band clamp for turbo mouthpiece whereas other kit reuse the factory weak worm gear clamp.

    - V-banded crossover pipe on the S400 outlet and stock turbo mouthpiece and the necessary silicone boot, not using one will cause boost leaks to occur over time with heating and cooling

    - PCV reroute

    - The kit uses our S475 turbo with the larger exhaust housing so it is unnecessary to wastegate the setup, spoolup is seemingly stock with this turbo in the kit.

    - Radiused T6 exhaust flange with a unique mounting setup that makes installation a breeze.

    -We use the correct designed flange off of the back side of the factory exhaust housing, they are CNC machined and are desinged to tightly slip inside the outlet of the exhaust housing and seal exhaust flow at the v-band connection.

    -High quality stainless steel v-band clamps and t-bolt clamps are used at each connection.

    -The hot side piping and exhaust housing are ceramic coated and heat wrapped.

    -The cold side piping and compressor housing are powdercoated color of choice.
