I want no drone at 2600-3000rpm, but loud otherwise is fine. It makes sense that a full 3' = Most power, and lighter is better... Markski, GMG, Tubi, Fabspeed, Cargraphic, Blah Blah....Help!!! Anyone in Maryland area with exhaust I can listen too would help, I will be at the PCA Summit Point track day on Oct, 30 too...Thanks.

 

Definitely go with Markski's @911tuning. He puts in alot of effort into those things and I don't recall the weight exactly but in the 25-28lbs region I believe.

Don't forget that these bad boys are 3". Not the 2.5".

Since you like it a little on the quiet side here is a catted one from Mark

I make tamer ones too... lol thats big kit no cats, tial WGs , venting dvs, and chattery race clutch...
here is what it sounds from the inside/outside... its all about the custom approach.. I make what the client wants..... this is the one no cats all 3" with custom made mufflers....

They're loud but good. I prefer cat-less 3" x-flow from Speed Tech or 911 tuning. If you're worried about low end drone maybe the Speed Tech with 100 cell cats is for you.

 

they are for those at 800+ rwhp but I make them in various OD as well as play with the sound by using louvered vs. perfed cores not to mention the packing material makes a big difference... 100, 200, 300 cell cats are options.. etc etc etc...

 

Lower weight is a plus too..

 

Markski is a great guy you can't go wrong going w/ anything he makes. Him or Neil Switzer, either 1 will be a great addtion to your car.

 

3" cat-less for most power. Maybe 2 additonal resonators afte turbos? Marek can make you a system.

 

this is the heavier of the two.... a tad under 30 lbs. and with .5" flanges, V bands, all 3" piping and custom mufflers that are heavier then my race mufflers.... 100 cell cats too...




next to a 60 lbs miltek that I took off for a client...

 

I saw your in car video w/ db meter at 93-95 db at crusing speed, that seems loud??

 

thats the ski850 kit.. with straight 3" no cats, loud ATS clutch... dvs venting wgs venting and the rear carpet was out because I was doing the 2nd pump relay wiring...

my 997 version is the same... heres is a sample of one... inside the cabin
stock 997 just chipped.. and thats more like it... WINDOWS DOWN...
100 cell cats, quiet street custom mufflers...

At 36 seconds I was hoping that the Jacklinks Sasquatch was not going to jump out of the woods.. But really it is a very good sounding system.
