I wouldnt. If I were you, when you do the install do this. Take off the Y-pipe, so your truck is open exhaust manifolds. You have to do this for the turbo install anyways. Then drill and tap the exhaust manifold for the thermocoupler. Then just start your truck up and rev it up a bit, sounds real good . Then go along with your install. It only takes 20 minutes to drill and tap an exhaust manifold like this, it isnt to hard.
