Man, that's a huge difference! Thanks for sharing that. BTW, although unofficial, doesn't it also improve performance? If so, what's the effect?
No HP gains, more expensive, and a little more weight, but I do not care because the sound is amazing! I now tend to spend more time in the 5-7K RPM range… the sound is SO addictive!

No gains? I test drove a Boxster years ago that had the sports exhaust and the sales guy said it boosted HP by about 8, but that it was "unofficial". Is that just total BS?
