Now that my CGTS mechanical problems seem to be abating, I'm thinking of replacing my secondary cats with Fabspeed pipes and reflashing the ECU at the same time. I'm within 3.5 hours driving time of Fabspeed and will have them do the work. I discussed this with Fabspeed this morning and they said I should net about 30hp and 30-40tq. They also claim it will it will wake my CGTS up.

Has anyone gone this route, did you notice a difference, and were you pleased?

 

I have the 2nd cat delete on my 09 turbo truck. The main improvement I have noted is in the exhaust sound. Not sure I have noticed any improvement in performance.

 

I have a 06 V6 and the cat delete pipe really made a difference!!! Sounds much better and hits 0-60 faster.....def faster!!

 

I think the remap will mainly change the throttle response.. for quicker responsiveness to pedal inputs. The ecu remap wont likely increase performance that much but it will feel more responsive and rev quicker. I would be skeptical of their performance claims until you see a dyno. Too remaps are so expensive for Porsche.. with my vw it cost under $400.
