RB header & presilencer w/ GReddy power extreme cat-back
I will tell you this much: it's very quiet at idle, quieter than with the manifold and borla twin cat pipe (minus the cat internals). Once you romp on it though, ears begin to bleed, both inside and outside the car. Just a little FYI for anyone thinking about this. Also, lots of top-end power gain, not really anything to report below 5k RPM.

If you think yours was painful think about my setup on our autox car. RB Roadrace header - Presilencer then exit stage right and left just in front of the rear tires. Our starters would have tears in their eyes. We finally took pity on them and put some Summit glasspacks on the lateral sections in from of the wheels and that made a huge difference.

yeah, I forgot to mention the removed exhaust diffusers in the rotor housings from my last rebuild. I guess from some of the people locally that I've talked to, they really do alot for noise...
