Happy to say after researching and listening to Youtubes,(which are subjective at the least) I went with Milltek exhaust on my C4S and I love it. Very nice exhaust if you are looking for more sound when you need it, no drone at highway speeds and nice idle. This exhaust in my opinion for street driving wakes this flat six up compared to stock mufflers. High quality, good fit and perfect added grunt for my 4S. My mechanic had no issues doing the swap. Nice Throaty deeper sound.

 

Great! Yep, I agree, a better sounding exhaust does add more grin. Stock sound is pretty lame.

 

I full heartily agree... it also causes poor gas mileage! I tend to drive at a higher rpm and get the Porsche rev'ing much as possible so i can hear the exhaust. The exhaust SCREAMS "PORSCHE" at 4K and above.

I have milltek headers with X-piped 200 cell cats along with PSE.....on my C4S.

You now need to go tunnel hunting.... you think it sounds nice now wait till you floor it in a long tunnel. The only bummer is that there's not too many long tunnels around where i live!! I need to go find some long tunnels in the Pacific Northwest.

 

Nice!! Can you post a sound clip?

 

Just youtube it and Vandersmith's clip will pop up
