Mine would pop ,like a firecracker sound when punched with the stock manifolds too. With the longtubes its really loud whenever it does it but I think it sounds cool. I read somewhere it has to do with fuel that was not burnt and doesn't hurt it,

not to say that this would have anything to do with the backfiring you are experiencing, but what kind of spark plugs do you have and how long have you had them?
I have experience the high pitched bang with my exhaust and then I changed my spark plugs to the #12 ACDelco Rapidfire, then no more back firing. If you are using the OEM sparkplugs, then the might be worn to the point of not combusting the fuel properly.
