what would be the best way to gut a cat without removing the entire exhaust system and what would be the best thing to use to clean the inside of it
1. your exhaust is going to sound rhaspy
2. Very little if any performance gain. Look at the in & out of your cat just inside the flanges, there's your bottleneck.
3. Unless you're boosted, some back pressure is good for your motor.
