Middle Muffler Options 90q20v

[David Thoresen]

Well after getting rid of my cat, I am amazed how much ooompf it opened 
up on the low/mid rpms...

Right now the stock center muffler is on the car, rear muffler replaced 
with just a small resonator, going out to a twin tip... sounds ok but a 
little "ricy"

Any suggestions on upping the ooompf level even more but keeping the 
noise at a quite rumble?

Thanks
David
