no, some exhausts are just like that, my pacesetter was the same way on my supra, i think its just from the sudden change in pressure from dropping exhaust gas velocity

The popping noise is from small amounts of unburned fuel igniting in the exhaust. It's perfectly normal during throttle transitions.

I have a MY02 Impreza RS 2.5 and its a perfectly normal noise. I am running a Magnaflow muffler with muffler shop fabricated cat-back piping.

If anything, its an Impreza Trademark to me
