The less resonators/cats the better. Even a Q300 style muffler can produce loud sharp pops. The Q300 on my FRS had a cat upstream, so it is quite mild.
The Q300 on my WRX wagon did not pop at all with factory cats in place, but once I got a catless downpipe it will produce ear splitting pops and flame.
Not sure what timing the FRS is running, but I have the WRX going as low as -15* timing as well as some tip in enrichment tweaks and adjusting the "in gear idle" timing
