Airbox to throttle body
 

I can't remember the company name but there is one that produces a smooth u-pipe for the airbox to the throttle body; just on its own. I believe it was three letters starting with A...not APR.

No I am not after HP, just sound..

Likely Agency Power. They have silicone kits for a lot of Porsche applications, or you could just fab up your own with Samco piping.

If it's more induction sound that you want check out this thread,

It removes the silencer chamber from the intake pipe, this is a virtually free mod and gives a very noticable induction roar.

Very easy to do too.

Got ya here.. It's aFE

Thanks guys......all very good options. I will check them out....I think it was aFE! I didnt know about ttp.

If one just leaves the stock pipe in how did these fellas plug the resonance chamber hole after removing it? I dont have access to machining equipment to make a plug so....ahhhh I see expoxy plug.....anyone make a solid removeable cap?

The TTP pipe looks nice! I was thinking of making something similar....but if it is already out there
