04-05 Duramax LLY SDP Twin Turbo Kit

$3650.00

Includes our 3" high flow Y-bridge kit
Completely TIG welded, makes for very smooth joints and the insides of the tubing are flush. We strive to produce the highest quality welds possible.
Custom higher flowing 3.5" mouthpiece that is also o-ringed to ensure there are no boost leaks where the mouthpiece mates with the factory turbo.
V-banded crossover pipe on the S400 outlet + stock turbo mouthpiece (no more cheesy factory worm gear clamp) and the necessary silicone boot whereas other kits don't use them and boost leaks will occur.
Includes valvecover vent fittings with hose and tee
The kit uses our S475 turbo with the larger exhaust housing so it is unnecessary to wastegate the setup, the spoolup is very quick with this turbo in the kit.
Radiused T6 exhaust flange with a unique mounting setup that sets our kit apart from the rest and 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.
