For a 2003 C4S:

Agency Power or PSE hack?

Thoughts? Discuss.....

 

FisterD or Gundohack is what most people do and are the happiest.

 

Agency Power & PSE hack are apples & oranges in comparison with regards to price.

My opinion is based on the muffler bypass that's on my 2002 996.
I love the aggressive sound rumbling with crackling is awesome.
I dislike the drone and vibration during acceleration.

From the videos I've seen the PSE hack seems to be the most cost efficient way to get the sound without too much interior drone and vibration.

 

Do the mod/hack for $200 ish and if you don't like it (I believe you will) then do the more expensive exchange.

Doing the PSE hack this week along with adding the LNE screw on filter adapter ans new painted bumperetts. Goes in tomorrow and should be complete Thursday.

 

I think you'll be happy with it. I like Fabspeed exhausts, but my buddy has them and I still like "my sound" just a bit better....louder and throatier. To each his own, but I really think you'll like them. Please post a video of you pulling away so more people can hear this....thanks.

 

Will do, I need to get some pics up as well. Just been busy and all, but fear not I will come through!
