Any updates if the combo of fabspeed cat-bypass pipes plus tubi exhaust would be prohibitively loud, or is it better to just do the bypass pipes as this seems to give better performance for a lower price. I have a new Turbo S, and the engine note is much too quiet for me. I know the combo is too loud on a Cayenne S normally aspirated engine noted in previous threads.

 

Bypass and Exhaust are a must have on the CTT. IMO It won't be too loud, the turbo's really suppress the exhaust note.

 

here are some setups you might like...

I have Cat Bypass pipes only. Love em. I would add the exhaust, but I don't really want an overbearing SUV on the road. I love the sound with just the Bypass pipes. I save the loud stuff for the GT2.
