Need advice on making boxster quicker.

Welcome to the forum!

Do a search on intake manifold and headers to learn all you need to know about "gaining" HP. You'll find it's expensive ($3-4K) and these mods are only worth about 20-30 hp combined. Not a good investment. Plus pay attention to all the references to CELs popping after doing these mods. A lot of headache for very minimal gain. Throatier mufflers fall into the same category. For the money you'd spend on these 3 mods plus what you've got invested in you box, you could probably find a 987S that would have just as much or more HP in stock form.

Believe the previous posters when they say the best bang for your buck is to swap engines with a 911. If that's not a possibility and you absolutely crave more speed, sell your box and get something else that fits your needs. Your bank account will be miles ahead and you'll be happier too.

Sorry for the reality check, but Porsches are not cheap. We don't want you to go bankrupt chasing a few HP gains.
