I would start by just purchasing the stealth muffler when you do the header/flex and see how you like the tone. You can always order an additional one if you want it quieter after that. a downpipe is for a turbo. The stealth muffler is $150 then then the cost of the header and flex is also on fswerks site. I just made this video for you so you can see how mine sounds a little bit and how it performs. As stated in the video the mufflers will not hender the performance in any way because they are straight through in design so they cause no restrictions. Keep in mind this is my phone so the quality is not so amazing but it will shed a little light on it for you(=
