perhaps. would this still provide the same or similar tone as going with the exhaust. will it even be that much louder since they would be catted and i would still have the oem mufflers? id have to really look into it

 

I have not heard the soul exhaust with the OEM headers. I was going to replace both but decided not to because the soul headers added enough volume and provided the sound that I liked. When the valves are open, it's pretty much a straight pipe.

 

I have aftermarket catted headers in LA and have passed smog 2 times so far.

Visually, unless you REALLY know porsche they look stock. Especially since mine are all beat up and have dents etc.

I have fabspeed ones.

 

interesting.
