[QUOTE="v65, post: 443220, member: 1773"] At idle the exhaust gases are in the right temperature range (1112F-1292F) that inducing oxygen into the mix burns the unburned exhaust gases. At higher temps, like during deceleration, you don't get burning you get booming, hence the backfiring. The induced oxygen then is a simple way to reduce emissions (at idle and cold running), except that for the end tinkerer it creates a maze of hoses and the backfiring. Removing the system is going to pump more hydrocarbons through the cat, which mean more work for it. Exactly how that effects the cat's longevity remains to be seen, but Dale Walker has an interesting solution for that. :devil: [/QUOTE]
