Well if it cost that much, then .... try to get rid of the cats if they don't check emission in where you are located. I got rid of mine cats a few days ago and just put on a straight pipe in there and I noticed somehow my Vulcan its kinda of faster than it was before. Even though I put on the rear muffler with Y pipes from a tec Sable I found at the junkyard. It sounds sweet.
