Can anyone help me to figure out why my gasket keeps blowing ! Its the gasket at the end of the ypipe..I have a nismo catback and a now a stillen ypipe if that helps any..I've replaced it atleast 4times in the last 2months..are there any long term solutions for this problem??

 

Make sure its the right size gasket.

 

Try some Vibrant gaskets. I've used them with no problems.
