For all Org members but specifically Ben Garner, Jamie and Chunger: I had the Magnaflow Perforated Core Resonator installed twix the cat and stillen muffler. Exhaust sound is much lower but only on an order of about 25% outside (Best Guess), interior cabin droning still apparent but more tolerable.....cat-backs on our cars I believe are inherently loud. I will live with it for now....but, I think the ultimate fix will be installing the stock resonator to really knock the cabin drone out completely. Hate to sacrifice free flow.

Thanks for your recommendations guys.

 

Glad to hear it helped (although not enough)...

I also put a short resonator (actually I reused one from the GReddy post cat that was replaced by the Magnaflow) just before the rear wheel... there is room for about a 12" one there... Believe it or not, it helps a lot too.
