Thanks guys, the car actually came with Fabspeed X-pipe (installed back in 2012).
Leading evidence: 'Install back in 2012)' (no explicit attributable resolution; this is a reported action or suggestion).

Is anyone familiar with this power kit? Feels like an attempt to recreate the oem x51 with a combination of parts. I�m thinking of trying it out price feels reasonable for +25hp they are quoting
EVOMSit Performance Software
EVOMSit TUNEit Module
IPD Competition Plenum
Porsche GT3 Throttle Body
BMC High Flow Air Filter Kit
OPTIONAL ADD-ON:
Cargraphic (can take additional 4-6 weeks to manufacture and import from Germany)

Wonder what the Cargraphic Add on is. Full exhaust maybe? I mean if they advertise +25hp it�s not so bad if you like tinkering with your car. Our NA girls won�t make a ton of HP for the price but the increase of �smiles per mile� is worth it to most of us.
FWIW, save yourself some money and time, get yourself a good set of 200 cell cats. That's where the performance boost comes from. The software improves throttle response on e-gas cars no real power gains.
The plenum and TB need headwork and porting to get any performance gains. Don't waste your money on the expensive air filter systems, get yourself an oem air filter and keep it fresh.
Hope it helps.
Thanks guys, the car actually came with Fabspeed X-pipe (installed back in 2012).
I went down the rabbit hole of exploring engine rebuilds to increase power (FSI, Slakker) this one is a long term keeper. I�m probably going to add a 997.2 coupe/TTS to the stable at some point but will also keep this one as my convertible.
where my head was at, X51 kit was a real thing that could get you +25hp over stock, if I could just reproduce it on an aftermarket basis, ~350hp for the cars weight is really solid and I already have other performance oriented upgrades such as Ohlins coilovers, swaybar, etc
the idea is if I can put this all together for $7-10k that feels better than a new engine which is 4x more
Cats, software will get you +10-15 hp. $3,000 for 15.
Plenum, tb, cold air intake gets you 0. $1,500 for 0.
Good set of equal length ported headers from a reputable shop may get you +5. $2,000 for 5.
The +25 number is BS with the parts list you provided, unless you get your heads done in addition to cats, headers, software, plenum & TB. $9,000-11,000 for 25.
Focus on your suspension, brake and tire set up, as well as driving lessons and you will have a fast car.
I have been chasing the holy grail for 23 years with all the bolt on parts on my 996.2. You can get big power gains, but you will need to spend 35-40k on a rebuild and head work to get it.
My best suggestion to you is spend the money on upgrading your exhaust, suspension, brakes, tires for performance now, and do all of the bolt on upgrades (IMSB, UAOS, fresh water pump, etc.) for engine durability that will transfer over to a rebuild when you decide to go hog wild.
Then make the rebuild the final icing on the cake. At the end of the day, and good suspension will run you $10k+, Exhaust $8k+, brakes $5k, and rebuild $35-45k.
IMHO its all worth it. Nothing better than a well sorted 996. But the +25 numbers that are thrown around with a couple of parts listed are just BS numbers.
I fall in line with GC996. Dyno says 200 cats, AFE headers (NLA), ported Soler 78mm throttle body, sport mufflers and software add 20 hp and 25 tq. 4 years ago all that cost me neighborhood of $2,900 on the cheap. Sound is greatest improvement, along with nice mid-curve torque plot.
Underdrive pulley and turning off a/c will net you a couple hp.
for sure, back when I was getting this done most places were out of stock / had long waits. Knew the price was elevated but didn�t want to wait an extra month to get the work done. The guys I work with are a local Porsche Indy and incredibly honest.
The other performance item to consider is an LSD to get the power down with both wheels. Adds stability during braking, turning and acceleration. Guard makes the internals for a 996. Its a must have item if you want balance, handling, and ability to carry more speed.
I know it�s not sexy to say but also keep an eye on our classifieds/marketplace. I bought might for 3200.00 shipped with Tarett hats, they had less than 12k mi on them.
