Exhaust Leak after installing PSE

[silberrosa]

A few months back, I installed a used PSE system on my 1999 911 C2 Coupe 6sp. As far as I knew, all was fine and the sound is dramatically better than the stock exhaust - I was actually quite suprised at how much louder it was. I did not install the electronics and do not plan to given the great sound. However, when I recently took the car for its inspection (NJ) they informed me I had an exhaust leak and therefore did not pass the car. My assumption is I must have not have aligned the sleeves / clamps appropriately on the exhaust pipe. Alternatively, should I have replaced the sleeves/clamps and not re-used the original ones?

Any advice is certainly appreciated - Thank you.

They didn't say where the leak was?

Could even be a bad header gasket...

They did not mention the place. However, I have had no problems in the 6 years prior (3 trips through NJ registration) to the install so my first thought was the pipes. Could be anywhere of course.

Sleeves from the muffler to cats is most likely then. Pretty easy to loosen and re-center the sleeves.
