After market exhaust for 2005 boxster S

[BruceH]

You can take a look at Top Speed, the owner, Che, is a great guy and a forum member. I have one of his exhausts and the cat delete pipes for my 2001 S.

You could also take a look at Fister or Fab Speed. Do a search of the forum and you will find lots of opinions

I have a 2001 2.7 and just installed the Fabspeed sport headers/CAT system, much more smooth, nice tone, and I feel a bump in HP

I will be installing their Maxflo exhaust next
