When I removed the muffler, the sound was a definate inprovement and you can read my Janurary 23 posting "exhaust already:heres the sounds" and you can see the you tube posting I did.

I first removed the muffler and gutted it but that did nothing to the sound even with all the baffels and 5 pounds of fiber glas removed, so I just added the stainless y pipe. It is all in the postings under my name including the limited slip differential upgrade photos.

Its on the rack now for a new set of heavy duty springs and I think it has gotten more miles going up and down this winter than on the road changing one thing or another like the Xenon lighting additions. Woody.
