I have an exhaust leak. I am thinking its coming from where the manifold bolts up to the motor. How much would it cost to get someone to replace that gasket or are there any other common problems that it might be? Thanks for the help in advance. I can make a video of the noise if someone needs it.

 

probably under $20 if you provide them the gasket at a muffler shop. You could do it yourself too - only 4 nuts hold the thing on to the engine . . .
