"Noise"
 

This is a quote form GT PurleyPorsche about the 997 GT3 Cup Car,
but I feel this way about my 73 2.4

"At times you have to wonder if Porsche hasn't deliberately allowed the flat-six to make such music as another test of driver ability: it's addictive to the point of distraction. To the point of holding the throttles wide open a nano-second longer just to absorb some extra noise-"Chris Harris

Just thought I'd share.

Yeah, I put a sport muffler on my car that to some may be a little loud. I personally can't get enough.
Just tonight I took my wife out in it. She said " Is it supposed to make that rumbling sound or is there something wrong with the
car." :D
