It seems like the 94 lost some power ( noticeable ) after i unbolted the cat-back. Is this true? Or am I just dilusional?

 

man, i have a 1997 Z28 with the lt1, i had my cat cut off a few weeks ago cause it was clogged, i feel like it lost power also, but not alot, especially on the launch, im planning on getting another one put on soon though, im getting an aftermarket cat that has more flow

 

You mean you're running no muffler system right now, just dumped after the cats? You're going to lose some torque, not to mention the ungodly loud noise you will be making will pale in comparison to how fast you're actually moving. Your mind is tricking you by making you think you should be going a lot faster. In reality, you're going the same speed.

 

I doubt you lost anything, I wouldn't worry about it.

 

Your torque curve probably just moved up in the RPM. Your making less torque down low but more power on top.
