For people that installed the cat back system, what other upgrades are you doing? Are there options for an air intake or does it not improve performance/throttle response so why bother? Also, how loud is the magna flow exhaust? Can anyone post a video of the sound on here?
If someone is of a mind to do so, and has the time, an organized list of available and upcoming performance upgrades to the 3.6 Premier/Rs would be great (including suspension, chip, exhaust, SC/TC, etc.).
