Stock muffler is to quite.

I’m always still surprised to see these trucks with stock exhaust

How my 97 was for a while. I had the 3" GM dual tubing, high flow cats into a Y-into a 3.5" tailpipe. When I put the Thorleys on it and started towing my travel trailer it was just too loud. For short trips, not towing I miss the sound. I had electric cutouts on it but one of the motors went bad.

So guys here's a big question. So before I fixed it up. When the exhaust was basically open manifolds it had excellent throttle response and pulling power. Now I fixed it its struggles to pull the same hill I could go 75mph on now it barely makes 50 with out pedal on the floor.

You can barely feel any pressure coming from the tail pipe.

Sounds like something is too restrictive. I am not a Flowmaster fan because they rob power.

I want to say screw it and cut it off. But my dad's like you need a muffler blah blah. I miss my loud sound.

I think your muffler or the parts of your exhaust that you did not replace are clogged
