Ladies & Gents,
I have searched & researched the forum and have not found any conclusive opinions/answers/recommendations to the following;

So, opinions, please;
I own an '09, 997.2 C4S and have already upgraded wheels/tires.

** With Tubi or Fabspeed airbox, headers and exhaust what approximate overall HP is the reality?

** Who has the better product for the money?

**What approximate gain in performance should I expect (in reality) if the above upgrades are augmented by performance tuning, predicated upon the tuning selected?
GIAC or another tuning solution? I think I prefer the handheld devise offered by GIAC. This is due to already owning a Hypertech device for my custom built Hummer and I am pleased with the results and flexibility.

The car is not tracked but is driven in a very spirited manner along fantastic mountain roads and the occasional long straight away that is irresistible
Any thoughts, comment, suggestions would be appreciated.
Thanks!

 

All of my research into this has been that gains are minimal, it's best to just do it for the sound improvements. I'd guess mid-range response might improve, but I can't see huge gains coming. Maybe Sharky, Fabryce, Casey @ TPC, et al can chime in to give us numbers. Lord knows they do a lot of these conversions.

 

Not sure about the actual gains but these do sound great

Hi & thanks! Yes they all do sound awesome and I will probably do the mods based upon the sweet notes alone.
After reading what I could find on intake & output, instead of 15-20 HP & greater torque advertised, I suspect something significantly less in reality. I would expect something, however.

The air-box intake, headers and sport exhaust augmented by either chip turning or the hand held devise by GIAC I would expect perhaps a 12-15 BHP increase that would manifest itself in the low to mid RPM range. If that is a reasonable assumption then for certain, coupled with the throaty, sweet exhaust note produced, then I would be satisfied and spring for the add-ons/upgrades.

So that's my question;
Is it reasonable to expect those results from the mods? Or am I just wishful thinking?

Thanks guys! I sure do love these cars!

 

With full exhaust + ecu, you DO gain some power and engine response for sure.
997.2 Stock system is still somewhat restrictive, and freeing up the headers + full aftermarket system will definitely help to gain some power.(Not just our system, just overall)

But your car is already near 400hp from stock and you will easily get use to 20-30hp gain within few days after the installation.

It seems to us that the great sounding exhaust system always gives more satisfaction to owners rather than some mild hp gain that most exhaust system offer on modern cars.

 

Thanks for your input, Jae Kim.

 

Jae sounds monstrous!!!

Yes, it does I agree.

Jae's product sounds great.
There is no chortling/congested sound as the engine reduces revs rapidly while parked. (say that 3 times fast!)
Love all the clips but would still appreciate anyone with knowledge or opinions of the best combo of tuning and exhaust with the objective of added HP/Torque. Exhaust note although inciting, is not the only reason for the Mods. The biggest part is the size of the grin when going beyond "full throttle" in 'Launch Control' !

 

Maxflo muffler (loud) + X-pipe
Car feels quicker in low range.. and awesome deep sound
Will post a video of cold start and max rev 3000 rpm
