This is a brand NEW, in the BOX complete 4" system. I went in another direction with my project and have this system left over. Never even removed from the box that it came in. It costed $662 plus shipping. I would like to get $500 plus shipping costs. Granatelli Motorsports #302540K This is also listed on eBay.
Unfortunately I’m in the market for 3.5” cutouts so not inline, but I’m curious which direction you ultimately went - was clearance an issue? Looks great, GLWS.
