Could someone post up what a stock 951 exhaust looks like from under the car. I am trying to see if mine is in the right spot or not.

Does the wastegate pipe touch the exhaust tunnel or is there some clearance there? Mine actually is touching the exhaust tunnel. Thats why I believe my car makes a clunking vibration type noise when getting on it.

I think my exhaust was hitting the rear sway bar and would rattle at certain rpm's or if it blipped the throttle!

My car has a horrible vibration/clunking ratlle sound coming from what sound to be the rear of the car. I replaced a lot of parts but most recently I have replaced my transmission with no change in sound. So now I am looking towards the stock exhaust is not mounted correctly and is shaking once warmed up at certain RPM's. It will hit the exhaust tunnel and make a noise. Not sure how to check if that is the issue or not. Don't know if I could drop the stock exhaust a little bit to eliminate that as the cause.

Stock wastegate has a support bracket which connects with the torque tube, but the wastegate itself should not be touching.

Now with my Tial 38mm + 1 pc crossover, my wg is actual on the torque tube. And I do get a clunking noise when engaging the clutch but I haven't had the chance to see what/why.

My car's exhaust is supposed to be all stock. Now I do notice some interesting welding work that was done. I'm guessing a testpipe was put in at one time and then they welded the cat back in before selling it.
