How can your truck run cool and free if it's choked on its own exhaust?
Your thermocoupler should be in the exhaust manifold, or the hot side, where temperature is 300 F (give or take) at idle. We don't care what the temperature is going out the pipes; we want to know what the temperature is coming off the pistons.
Now you may be thinking that if the thermocoupler burns or breaks off, it will wipe out the exhaust wheel of the turbo. This just doesn't happen.
If you can't put your arm through it, you don't want it in your exhaust system.
Some truck manufacturers are using a reverse flow muffler. This has got to go. Do you remember rounding the bases when you played baseball? You didn't run to the base and make a sharp 90-degree turn and run for the next base. You rounded the corners so you wouldn't have to slow down. Now remember when you tried to stretch a single into a double and the infielder was standing there with the ball? You had to stop and scramble back to first base.
Well, what do you think your exhaust has to do in a reverse flow muffler? It's an exhaust dam. The end result is higher EGT's and the engine running with too much back pressure. High back pressure results in poor fuel mileage. Same principle goes with the bends in the pipe. The less extreme the bends are, the better the exhaust will get ride of the gases.
