My Invidia exhaust was very quite before, since I replace the new gaskets my exhaust become very loud and I can feel vibration under the whole car. Does anyone know what cause exhaust loud and vibration? Is transmission mount? my car is automatic. Thank you.

 

Are you sure the exhaust piping isn't now resting on one of your braces or pressed up against the body underneath?.. I would check that possibility first. Then check your exhaust hangars.

 

So easy to just get the car up on a lift or something and look around with another pair of eyes to help you. Make sure the gaskets were installed correctly and the bolts are on tight. Also check to see if the piping it touching anything or if there was something left loose from the installation.

 

Yes, I just booked the exhaust check tomorrow lunch time.
Will let you know the result soon.
Thx.
