Jimmy, I think they are planning on cats after they get the race headers up and running. Could be wrong.

Think last I heard they were doing GT4 Race then 911 and possibly catted GT4. I could be wrong though

Hi guys,

Race system first, then 991 catted. Then a full system for the GT4 including cats.




Tacked up GT4 Stepped Dundon race headers

HJS 200cpsi HD cats, spiral wound for durability!

The catted system will be a complete system with a new muffler, valves, cats etc... We want to preserve as much of the performance of the headers as possible so we're building the catted system around it. Will also offer the full exhaust without cats...

Are you moving the catalysts to the other side of the axle like FVD does with their CS 100cpsi system, so that the long tube primary design is kept?
Please also offer a minimal weight valveless muffler, with straight pipe or cylindrical resonator options.
Gloss black 89mm double wall slant cut tips like stock preferred.

So pumped to see the full system and dyno! Great work!

Ceramic coating as an option direct from you guys would be great too
