This guy I know just got a Magnaflow Cat Back system for his Si, and he posted some clips of it here: http://www.honda-tech.com/zerothread?id=603993

I think it sounds great, and from what he tells me, its an all around great exhaust, Im surprised more people dont have it too, because you can get it for around $300 shipped off ebay. I think when I get another car in a few months I may have to pick up one of those :biggrin:

The best way to view the videos is by saving it then opening it with Windows Explorer, otherwise it will try to open it with Real Player which doesnt work.

That exhaust sounds awesome! Nice low throaty tone. I'm assuming there is a cool air intake adding to the overall noise, but the muffler sounds great. More like my friend allans WRX which has 2.5" piping, and alower tone resonator. I wish I knew about this before I bought my Tanabe (Which is very nice but has I higher more whiney tone).
