I recently purchased a Fabspeed Gen 2 (I don't mind the drone one bit, believe it or not, lol) and had it installed on my '02 996TT. When I picked it up from the shop, I noticed it sounded like it had an exhaust leak. The mechanic said he tightened the clamps correctly and even moved some around to see if it made a difference. It quiets down when the car is warmed up, but does not go away completely. I was wondering if anyone had a similar problem and what they did about it, or even if anything else can be done. TIA

 

I had an issue with a loose o2 sensor on the Fabspeed Exhaust (997tt) .. I would suggest checking if they are installed properly and tight.

 

did they replace the aluminum crush rings on the turbine housinf during the install. I think they can be reused btu maybe one got whacked or was not reinstalled. good luck.

 

Do you have aftermarket headers? My headers were leaking bad!

 

Stock headers, as far as I can tell.

 

Where was the leak from your headers coming from? How did you fix it? I hear something that sounds like an exhaust leak after having my headers put on.

 

I just remembered, the exhaust had the "vortex cones" installed. Could they have been welded on wrong to cause a noise like this?
