what is backfire, from what i have been reading from the net, and from what my friend (he is real good aboutcars) say, it doesnt seem like backfire, it kinda gives the exhaust a growl right when you let off the gas!!

actually i should have said backpressure.

backpressure, is that bad, what is it?

backpressure, i think thats exactly what my friend said too

i would have to hear it, but back pressure is the resistance the air
encounters as it leaves the cylinders and goes down your exhaust.
