I know magnaflow sales a street series and a racing series. I know what a warpspeed y and b pipe sound like with a street series muffler, but how would a racing series muffler change the overall sound? Anyone with a magnaflow street series muffler? or another racing series muffler? whats your setup and whats your sound like ?

 

Racing mufflers are usually marginally freer flowing than street ones. The noise decibel is also a lot higher on race mufflers. You can get something like a APEXi N1 and get a silencer for it. But that really defeats the purpose.
