Did an intake/header/exhaust on my KA24DE in my 240... just out of curiosity, is all the popping normal? I know my Sol used to pop every now and then, but this thing sounds like a damn lawn mower or something lol. Just wondering if this is something that is common with a new exhaust/header, or something I should look at... the secondary o2 sensor had to go bye bye because of the header, so it's probably dumping in a bit more fuel than it should be... but other than that everything appears golden. LMK about the popping please!
