On my 240SX SE, I have the TTV6 swap, and the Rocket Bunny body kit. However, whenever I let off the throttle, i hear the backfire, but no flames come out. I don’t know if it is the car, the bodykit, or the engine. Any help?
The exhaust combustion is so high that it ionizes the gas molecules and produces a blue flame… which you probably won’t see during the day. Try it again at night.
(What? Sounds legit to me.)
