Keep blowing exhaust fuse

Here's the story:
Yesterday morning I went to the exhaust shop and had my resonator cut out and shortly after leaving I blew my exhaust fuse.

Didn't worry too much because it worked fine for a few hours....4 fuses later (even higher amperage ones) it will now pop a fuse pretty much any time I go over 3k.

Once the fuse pops the cruise doesn't work and the gears I shift into seem to take a while to actually engage. Everything is fine when the fuse is good. I checked every other fuse and they're all fine too.

I don't know how the resonator delete did this but someone please help

Um NOOOO

Thats not the exhaust fuse. Clutch Pedal sensor and a multitude of other things are covered by that fuse.

Exhaust fuse doesnt even make sense.

Check you o2 sensor wiring. Make sure its tucked in the exhaust shield. There's a lip for it to sit on. It may have chaffed together to cause the short. I know my 1st o2 sensor caused this for me.

It doesn't. I just couldn't think of anything else "EXH" stood for I guess.

exhaust fuse

That's the one that controls the high speed muffler bearing.

it's right next to the blinker fluid sensor fuse right?

He's most likely referring to the fuse marked EMS ( which is emissions )

that is the exhaust emissions fuse.!
It connects to your O2 sensors your map sensor and the evap purge solenoid.
it is most likely grounding out somewhere in the wiring.
