it isnt ripped. to make it more snugly fit, i fitted the exhaust port groove with silicone rubber before inserting the gasket.
today i run my CT5, and now get a small idea. holding the car in one hand while revving it up, i noticed when i open the throttle, some smoke comes out of the exhuast port while some come out of the pipe itself. i rechecked the exhaust gasket and made sure it isnt not ripped and sure its fit and perfectly smooth but cant understand why in the world it keeps on puffin smoke in the port while revving...geeze, guess i need to change another gasket.
