I have a 97 mustang gt and have very few mods done to it. They are underdrive pullies, xpipe, flowmasters, MSD plug wires. After i had the exhaust put on it started making a poping noise at a high RPM ( 5500) so i changed the plug wires and plugs thinking this could be it but it is still there it doesnt do it all the time but still does it. Does anyone know what can cause this or how i cna fix it ?

It does it when i am accel. it kinds sounds like back fire and it shots a flame out of the tail pipe and i am wanting to put a nitrous express kit on it but i dont want to mess anything up. I had someone tell me that it coudl be the smog pump but my car does not have one...
