Out of all of the aftermarket exhaust systems out there I would recommend doing the Gemballa headers, high flow cats and the muffler. It is by far the best sounding throatiest sounding exhaust for the boxster available. however it is probably the most expensive. It cost me about 4500 to upgrade all 3 on mine and it sounds awesome. The Gemballa kit is very well made and stainless steel throughout so looks nice from the rear end.
With this and a good air intake, my preference is the T-T-P intake, I would suggest having your ECU enhanced by having your ECU reprogrammed on a Dyno so your air/fuel ratios dont get out of wack.
