Catalytic Converter Removal |
 |
| Removal - It took me an entire
afternoon to cut the cat off with a hack saw and install the new pipe. The
downpipe and Cat must first be removed by unscrewing the two oxygen
Sensors, the clam clamp and the three bolts at the turbo housing. I then
used a hack saw to cut the Cat off just inside each of the welds. I sanded
both ends and slid the pipe with exhaust sealer over each end. I secured
it with the two circle clamps and drilled a hole in the pipe to hold the
second oxygen sensor. There was noticably quicker spool up with out the
cat. Cost: 15$ Pipe, 2 Circle Clamps, Exhaust Sealer Time: 4 hr Difficulty: Moderate |

| Disclaimer - I do not want to
recommend this modification since it is illegal, however I do think that
it is a better way to go than gutting the Cat. There was a noticable
increase in the sound level during idle which I liked, but during
acceleration it becomes extremely loud. After three months I was tired of
the sound and reinstalled the Cat. I have decided that the best solution
is to install a 3 inch downpipe with a 3 inch high flow catalytic
converter. * Do not perform this modification if you have a naturally aspirated Saab. The decrease in backpressure will cause a decrease in performance and gas mileage. |
