I have in great condition Stillen cat-back which is single tip(ZR) mufflers with the x-pipe. They still shine no dents and still says stillen on it. It is 2.5in, I got a 3in cat-back so I have no need for the stillens. They served me well I absolutly loved them, very quiet but has the performance to back it up, I spooled very quickly. It does not come with the gaskets. I would perfer something local I am willing to drive a distance or meet half way. Email goes straight to my blackberry. $550 +shipping and paypal fee if necessary. I can get a discount on shipping with the use of my mother's workplace discount.
