i backfired rreally loud with a cat!! and Q about greddy BOV
I love all the people who say "it can't damage anything, I like it"
First, it can destroy a cat pretty quickly. You can introducing a flame front to the catalyst.
Second, it can destroy the O2 sensor just as quick.
There are really 2 types of backfire. One happens at the exit of the system with the introduction of cold air to the hot exhaust gases. The second is an exhaust leak somewhere in the system that sucks in cold air when you go off throttle. This type can do a lot of damage because the room to expand is not open to the atmosphere like the first type. I have seen mufflers split open from just one backfire. Gives you and idea of the force invloved.
