I was helping my friend take off his stock exhaust off his 97 gst, and we finally got it off after some cleaver jack work by me.

(That damn muffler is ultra gay getting off of the rear axle!!! The damn thing needs to be jacked up very high to get it off!!!!)

So we drove around a little and man that thing didn't like to rev. I'm thinking we were running mad rich, hehe.

Thermal 3 inch goes on tomorrow when more light available.

 

Sawzall's are excellent for getting stock exhausts off, just cut and remove.

As for the 2nd O2, it's only there to monitor catalytic converter operation, it doesn't have any effect on the tuning.

 

Really?!?! I thoguth the second 02 sensor had some effect to the car's operation b/c it really wouldn't rev.

 

I havent had a 2nd o2 sensor for years now and never a check engine light or other problem with it
