So I went to start up my car today and my started up really loud and weird
, after running for a bit it seems to go away/get much softer
. Anyone recognize what it is? Is it just an exhaust leak or something more? Btw I have a fabspeed exhaust if that makes a difference.

Yep it sounds like an exhaust leak. As the pipes and joints heat up, the metal expands and closes the gap, making it softer.

Get underneath the car and make sure the exhaust manifold fasteners are secure (torqued to spec). If that doesn't take care of the issue, you may need to replace the exhaust manifold gaskets.
