Has anyone ever deleted the cats from stock pipes? If so, what were the results? good.... bad..... louder...... no change?

I dont think it would be bad, just give you a check engine light from your o2 sensors not picking up what it is suppose to. I was debating about cutting out the 20" cats and making a 20" H pipe in thier place.

H-Pipes are so cheap why butcher a Cat. pipe you may need later
