While it is true Motordyne and Fast Intentions have seen the highest gains, we are talking a few hp difference compared to others. Remember that turbos will act as mufflers too so don't be afraid to go aggressive. With the headers though, if you do get Fast Intentions, opt for the 12" at a minimum if you don't want rasp. The Motordyne exhaust should be good. be aware that header will change the pitch of your exhaust to something higher. It will SCREAM. Shovelman has vids with PPEs and fast intentions with no resonators. I have mine mated to a Tanabe exhaust and a HFC in the Y pipe. You'll notice even with completely different exhausts, you can hear similarities because we run the same headers.

The intakes imo, again they are within a few hp of eachother, especially after everything is tuned. I personally like the AAM intake design. They have a sleeve you can insert or remove to adjust the pipe size at the MAF. Once you go to get the car tuned, just remove the sleeve. As mentioned above the Stillens actually have a good rep for their intakes.

I have vids and dynos in my journal. Some newer vids are in the last few pages. Best of luck, it's like Russian roulette when trying to figure out what your exhaust will sound like when you add headers.
