Anybody tried other brands of crossflow mufflers besides Flowmaster? Not to get me wrong, I like the sound and the responses people have about Flowmasters, but I want to know if other brands have been tried.

Thanks in advance.

 

I like flowmasters - what about Magnaflow? I hear they give a good rumble but are fairly quiet. Don't know about on a Z though. =\

 

I noticed also that Buick Grand Nationals had crossflow mufflers. I wonder how the Z would perform with one of theirs.
