ok i did a search and got nothing..this might even be a noobie question and i have no idea at all!. Maybe i am over reacting, but sometimes when i shut off my car the exhaust pops when the engine has been turned OFF. Only sometimes it will do it. I am running a DP, HF cat, and a RB dual catback. Should i be worried????

thats odd, how much longer after its been turned off?

Could be a weak coil, or a leaky injector, Mine did the same like 2 to3 seconds after I turn off the key. I ndrove it like that for years, no problems. Recently I put in new secondary injectors and got an ignition amplifier, and I noticed the poping no more.

Mine does this too sometimes. I figured that it was just a backfire from the last bit of unburned fuel that gets kicked out of the engine once the ignition is turned off.
