That's an awesome improvement considering you only did an intake and I am assuming when you say "exhaust" you mean mufflers correct? In other words your cats and headers are stock?

You should get cats done and then have a tune to match your mods and you'll really be surprised with the power gains you'll see afterward!!

Great pick-up in TQ, too. That's what you'll actually feel imo.

 

@perk10: yes, mufflers only -- rest is stock.

 

Is that picture your engine marlon? It looks like a 997.1 engine and your avatar says you have a 997.2....why dont you share your exact pic setup?

 

slicky rick: the cold air intake was installed on my previous Porsche, which was a 997.1. My recent car is a 997.2 and that one doesn't have the air intake

Speaks to the validity of the dyno.

 

+1, very misleading, intentional or not

 

I've got the dual intake on mine and it absolutely screams in the higher parts of the rev range. I had people saying it sounded better than the GT3s running around when I did a track day last year. I've got Fabspeed Headers, high flow cats, and the intake. My 2007 was pulling on a 2011 GTS on the straight at Road Atlanta so there is for sure quite a bit of gain from these three items. I've been meaning to get a dyno just haven't had time to go.

 

I've wonder how the dual intake would sound. You answered that. I couldn't take the sound nor could my wife. So out it went not to mention there really wasn't any gains to be had.

I would have to say maybe the other car wasn't going as fast hence you appeared to be gaining up or away...whichever it was.

I was on the freeway Saturday and I passed an Infinity G35 couple(I think). I was already going about 75 and wasn't racing but he wanted to and he just pulled away when he caught up to me.

I'm thinking he was a sleeper with a turbo because I could see the lag and then he blasted ahead. I didn't engage in the high speed racing because I want cornering speed and not straight line speed. If I wanted that, I would get a 'stang or Vette.

Make the car handle well not trying to keep up with GTS, GT3 or Turbos. Everyone has what they like on their car. Good luck!!

 

I have the same set up and it's awesome. Looking to add x pipe, plenum and ecu flash.

 

Added the plenum, GT3 TB, and X51 airbox/BMC...no noticeable gain, sound ok in upper rpm range.

Added the FVD 200 cell cats and FVD headers for PSE, that woke up throttle response, acceleration, sound...she run *good*.

It has been a while since those perf mods, maybe an ECU tune...maybe. Do have the TT in mind.
