Where to start? Performance upgrades . . . .

[spooltime]

New to my CTTS, and have been perusing the various boards looking for ideas regarding things to "upgrade" it. A little more power is always a good thing, so I've sort of narrowed my focus to starting with either a i) secondary cat bypass set-up (probably Fabtech unless someone can suggest a better alternative); or ii) an IPD intake plenum. I'm interested in opinions of those who have done one or the other (or both), and your recommendations as to which is better as a first mod. TIA.

I've done both and a Eurocharged tune on my CTTS. Slight, very slight difference with the Secondary Cat's but the Pig sounds so ever slightly better with them removed. IPD Plenum, I got a great deal, found it on Ebay as closeout for almost half price of retail and can't really say I notice a difference but my stock (Cheap crappy) Plenum was showing some delamination of the plastic when I removed it. The Eurocharged tune was mostly a throttle response improvement, slightly noticeable increase. Keep in mind the Turbo S is the same engine as a regular Turbo, just bigger Intercoolers and higher stock boost so most aftermarket tuners can show a larger increase with the standard Turbos but there isn't as much leeway to work with on the Turbo S as Porsche already took up some of the slack.
