This is a complete never used kit. Pn 05177 for 1998 thru 2002 LS1.
Comes with a 15lb bottle. We started to install it for a customer, but he decided to go with a bigger kit. We cant return it because it is not in its sealed package. Again this kit is brand new, never used. Will sell for $550.00
This kit sells at summit for $594.00 plus $11.95 for shipping. You can either pm me or call us up at the shop at 810-412-5198. Thanks!
