In these steps you will remove the stock exhaust
system.
1. Use a sawzall to cut the exhaust
immediately behind the muffler.
2. Then cut the exhaust 4 inches
behind the catalytic converter in front of the band
clamp.
3. Unbolt flange in front of the catalytic converter.
4. Then make a cut at the bottom of the down pipe.
5. Finally cut the bolt on the firewall so that the new
down pipe will fit.
6. Use a 7/16” deep socket to loosen the stock bank
clamp at the top of the stock down
pipe. The stock band clamp will
be reused, so you will not need to
completely remove it.
7. Remove each piece of the stock exhaust system,
including the stock hangers. To make removal
the hangers easier, it is recom-
mended that you use a silicone
spray on each of the rubber
hangers that hold the stock
exhaust.
