Speaking of the exhaust. The exact one I have is still up on ebay, but I came across these versions of it with a different muffler styles and painted black. A bit more expensive, but not terrible.

They all have dB killers. The second one has a bigger muffler and the hanger may even just barely reach the stock muffler mount point on that one. The mid pipe mount still needs modification on them from the looks of it.
This is another seller with the exact version I bought, unpainted. No DB killer with this one either, but it's also less than $100

Unpainted with a "Carbon Fiber" version of the second black system.

And a different seller that I linked previously, just to concentrate all of the links in one spot.

The inlet baffle I used. Probably the best designed one I have seen in regards to flow capabilities. It does indeed make a difference. It's not a huge difference, mind you, but it takes the edge off the exhaust note a bit and probably drop it a couple of dB.
