Any detectable smell from the car? Just curious. I know that it can cause a smell, but I didn't know how bad it would be.

Thought about going catless in the past.

 

Yes, you can smell its catless now. Every car I've ever gone catless on (this is my 5th now) you get an increase exhaust "smell"...992 is no different.

Is it bothersome? That depends on your nose and your sensitivity to the smell. Coupe or cabrio obviously makes a difference. 90% of the time you will never notice it. Idle at a stop light for a while with the top or windows down...you'll notice it.

 

^ Are you feeling any power/torque difference?

 

I'd like to say I feel more power but its all placebo I'm sure. A louder exhaust always "feels" faster LOL.

Dragy results show near identical 0-60 times before and after air filters/cat bypass pipes. 0-60 is not the best performance metric but its all I've tested.

 

Same - I finally got around to redoing 0-60 after installing my fullback exhaust (high-flow cats, not bypass), and the times were identical. That said, rolling/mid-range pulls do feel much snappier and quicker, but I have no way of quantifying it.
