I'm getting excited... Mine ships in a day or two.

 

For me the anticipation was "killer", but well worth the wait. Enjoy!

 

I had my 3" 911 exhaust with 100 cell cat installed yesterday with twin 3"" tips. I had a 70 mm exhaust with 200 cell tips prior. I am speechless regarding the sound. My mechanics and I find the sound very exotic like a GT3 mixed with ferrari and lambo. Even if I lost a little power ( which I didn't ), I would have to recommend this exhaust to anyone.......although I'm hoping to sell my old exhaust locally, so I may downplay the sound til then lol. Like others, all my changes were Markski directed......What a terrific guy to work with, and such a wealth of knowlege. My hat's off to him and his products!!

 

So did you end up going with his custom sport mufflers or the 'off the shelf' race mufflers? I've got the same kit, less the cats, coming to me this week or next...

 

I got the custom sport mufflers I think. Because I did the upgraded turbos, intercoolers , intake etc. I just bought what Mark suggested to make the most of my car, but get of the bit of drone I got with the other exhaust. Good luck with your car...... you will be happy no matter what he sends you
