Ok i just got this thing maybe 1 to 1.5 months ago... All it is is the prochamber itself that bolts on the mac mid pipes that come with it. So you would either need to alrdy have the mac mid pipes alrdy or you could have it welded in your on pipes. There are 2 bungs for the 02 sensors on this piece. Il post a pic up tonight. Nothing is wrong with it i just had mac send me the h-pipe section that is a direct fit and to me the h-pipe is the meaner sounding. PRICE $125 SHIPPED
