Just wondering what the most practical way to do this is. I wanna put new high-flow cats on the car to go with a new exhaust setup. One cat looks easy enough to cut off. The other is welded to an exhaust manifold and looks like it would be a real PITA to cut off because the connection is up high where there wouldn't be much room for a saw/grinder etc. I suppose I could try to hollow it out, but I don't want to do that for various reasons(potential flow issues/Looks ugly/hazardous dust)
