Hi all. Just installed a new Agency Power exhaust in my 2007 Cayman 2.7. I did the installation with my son. It took me couple hours but it was not that hard. I have to say it is not that loud, I think it is even more civilized that the stock exhaust. The sound is sportier and deeper. Great sound! The more I drive the car the better the sound. Then it gets loud after 3,000 RPM. But the biggest advantage is in power. The power boost is noticeable! The car accelerates faster and smoother; the back pressure is completely gone! Wow. This is great power and sound for a fraction of the other exhaust out in the market. The pipe tail and chrome exhaust can be seen from the back and it really gives the car an aggressive look! Next, the K&N filter. I will post pictures soon. See ya'll.
