Smells like gasoline (love it) and it pops and spits flames when heated up and revved. No CEL so far and I've had it on for a few thousand miles.

I do not just shoot fireballs, I can do continuous blue flames at night from the exhaust tips, when running nitro-methane in the water/methanol injection system.
