Real Fiero Tech

I've got a 3 disc, 3" Car Chemistry exhaust insert. Its got like 500 miles on it. I also have the stainless steel wadding you use to make it even quieter. The 3/4 inch center plug and totally flat center plug have never been used. I've even got two decals for it. I've got like $80 in it. I switched to a dual 2 1/4 inch exhaust setup. Anyone need one of these?

Out of curiosity, how did it work for you?

Mounted 1" in from the tip, not all that well. The closer to the motor the better they work, but I had a 90* off the motor then a 90* into a muffler, then my tip, so I was limited on placement.
