Exhaust Leak Help

I just installed the AFE 4 in tubo back full exhaust system. Now I have a massive leak which sounds just like a broken exhaust manifold leak in a gas engine. I have checked the manifod, and replaced the gaskets on the manifold. Additionally I have repaced the Doughnut gaskets on the turbo exhaust intake pipes that run up the back of the engine. I have gone to a few exhaust shops and they have told me that I am hearing the exhaust in the much larger pipe but I dont believe them. Does anyone have any Ideas where or how to fine the leak.

Did you check the turbo clamp, sometime if you dont get the down pipe just right it will leak.

Can you see any soot around the pipes, or joints another thing you can do is run a stethoscope over all of your joints, and gaskets that will be very loud however. But these things do sound alot different with an exhaust on them.

not if it's post turbo!


Since it happened AFTER the exhaust install, I'd presume you didn't get the Downpipe clamp all the way on...

Maybe a soundclip will help us? Or a video? Or find someone locally to give you a hand that's been around for a while! Try the AZ threads!

Thank You

Thank you all for your help. I am going to try and reclamp the turbo clamp and also listen to the seams. I have not seen any soot from any of the joints or gaskets. Thank you all again.
