Looking for a few technical opinions here (not political ones )
Would it cause any problems if my catalytic (sp?) converter fell off and I put in a straight pipe? O2 sensor is before the the cat, so it should be uneffected right? How about back-pressure?
Now, I try to keep my car as original as possible (other than the turbo set up I'm looking into ) But I'm just curious. I am not exactly looking for a hp advantage (it would be like, what, 1 1/2 hp), I am more looking at not spending the $1100 for a little while longer (and a little growl is always nice ).
Any comments? Warnings? Cudos? Admonishments?
Thanks!

You will need to replace it with a muffler to reduce the noise and retain the back pressure -- else you risk burnt valves and it will be louder than stock.

Some performance enhancement will ensue, but these days the restriction of the converter isn't what it was originally, there won't be a huge gain.

Use an aftermarket catalytic converter and save about $950.00 and be legal with probably improved flow to boot.

Any muffler shop can do it.
