$310.40
Description
A cold side pipe that holds boost
Wehrli swaps the two-piece plastic factory passenger (cold) side pipe on the 2017-2019 L5P for a one-piece 3.5 in. pipe in 14 ga aluminum.
A CNC-machined flange with twin O-rings seals better than stock, and the factory clip ring gives way to a silicone boot with stainless T-bolt clamps, so the joint holds more boost without leaking. A threaded bung takes the factory intake temperature sensor.
It bolts onto a stock truck: no other upgrades or tuning needed.
Who it's for
2017-2019 L5P owners who want to put an end to blown boots and boost leaks on the cold side.
