I have the Garrett Powermax turbos and the AMS inlet tubes. For those who aren't aware, the Powermax turbos ship with two sets of inlet adapters - one set will work with the OEM size inlet tubes that have a roughly 1.75" opening, and the other set is sized for a 2.75" silicone coupler.

The silicone coupler is a weird angle somewhere in between 45*and 90*.

Has anyone found an appropriate silicone coupler to work with the larger adapters?

I know this is a bit older post but it came up with my keyword search. I did the same mods to my truck recently. Garrett Powermax turbos, AMS inlet tubes with the larger silicon adapters. I was wondering if you had and issues with throwing an emission code. I keep getting P144C "purge performance under boost" after the installation. I've been trying to solve it with no success.
