For to anyone thinking about this, you'll see an instant difference in intercooler performance and in turbo whistle. Instead of blowing up like a balloon, this solid pipe delivers pressure as soon as the turbo spins up.
To install, be sure to unplug the ECU connectors just above the lower intercooler input to give you room to work without damaging the wiring harnesses. I did my best and took my time and I still ended up with a few battle scars on the pipe, but I didn't do this for looks.
Great product and I plan to buy anything these guys make for the '21 L5P!

Happy with the single hot side pipe. Shipping was fast. Installation was a breeze with the included instructions. Maybe an hour taking my time. (Be sure to disconnect the ECU plugs for additional space). Note* be sure to disconnect the battery before unplugging the ECU harness or you will get a CEL. Leaving the bubble wrap on definitely saved me a few scratches when fitting it up the wheel well. Clamps tighten down great. Happy with the purchase and install experience!!
