I'm currently running a Magnaflow catted X with a Magnaflow cat back. I like the Mag cat backs as they give a nice sound without any popping and minimal drone on the highway, but I'm looking for a deeper sound, rather than the slightly raspy sound that the X provides. So I'm trying to find a good, high performance catted (needs to pass CA smog) H pipe.
Also, from what I understand, X pipes a freerer breathing in the upper RPMs which provide more power up top, whereas H pipes, give more torque down low, but are more restrictive up top, is that correct??
