So I just got a used jic y pipe and the flex pipe mesh part is scraped/scratched off.. It's only on one side of the pipe, The guy said its fine and it's just the mesh that holds it together. So I'm wondering if it's fine? Or do I have to fix it

 

Only one way to find out. Install it, start the car and see if air leaks out.

 

Oh alright and if it does leak can I fix it 0.0 :[

 

its prob fine. My flex joints on my hks h pipe were all torn up, and had no leaks
