So I wanted to pump up my volume a little bit, and after reading about the different options on the forum and tring to find sound clips on youtube I started making changes.

I first removed the secondary cats....A little bit of sound gain, and maybe a little bit of "seat of the pants" performance gain. (The cats do produce back-pressure)

I wanted a little bit more sond so today I removed the resonator, and WOW did it get louder! Too much so..... Tomorrow I will either reinstall the resonator or the cats. I think the performance would be better without the cats, but the sound may be better without the resonator.

I am making film clips of each combination that I try and will post them when I am done.

Yea. i've been listening to the Youtube slk sound tracks as i want to enhance the sound a little. One of our fellow members (TrevF) lives close to me & has had the resonator out for a X pipe & loves it (see his post of yesterday in the AMG section).
Look forward to you posting the sound clips.

Hey Doug - great info - I pulled the cats, replaced the primarys with highflows, deleted the secondaries, installed headers, etc. I'm right on the edge of being civilized - I may just try popping the resonator back in to give it a try..
