Default Hesitation Under Heavy Acceleration

This just started today. I have a 1987 with a manual tranny, and I just had a full melrose exhaust system put on it with corsas and it was sounding and running great all yesterday and this morning.

Now under heavy acceleration it hesitated and doesn't accelerate as fast as it is supposed to. It has a new knock sensor and wire, new EGR, new plugs... Anyone have an Idea what it could be? Everytime I get my car ready to drive there is another issue haha.

The hesitation begins around 2000 RPM and doesnt stop unless I let up on the gas.

Well I checked for codes, and i had a code 46 which was with the alarm or something so thats not the problem. The parts store guy thought it was most likely the fuel pump...

It just has no power under heavy acceleration!

Problem Solved! It had a very clogged fuel filter... I also replaced the fuel pump.

It drives great!
