GEAR HEADS HELP! Rapid exhaust popping @ WOT high rpm
I could use some help guys. My cobra starts to rapidly pop when I step on it hard at high rpm, anything from 5000 and up.
It has no loss of power, matter of fact it pulls like a beast. Other than the popping it runs and idles smooth. I'm not hearing or feeling any misfires.
Any ideas of what this could be? I was thinking maybe an ignition component like plugs or coil packs. Maybe the spark gap is too big and the car is running lean. I get no codes. I am running msd coil packs and I also have an off road xpipe which I thought may have been a contributing factor as well. Your input would be greatly appreciated on this one thanks.
