I changed over to a 911 4S and had to put the stock exhaust back on before selling it to Porsche on the trade in. Paid 2200 with tax. Sell for 1100. The sound was so much better than stock. No drone on the freeway and fun from every stop light. Going to put one on the 911. All you need is two triangular cat to exhaust gasket. It took me about 2 lazy hours to install. easy bolt on.
