i have an exhaust leak at Y-pipe/collector. there is already a C clamp thing on it and i don't know what else to do. its a slip on piece and i've tried to push it in all the way but it still leaks. any insight would be great.

thank you

 

this is on my pacesetter headers and y- pipe

 

Get it welded?

 

what if i hafta remove it? i'll be going thru clutches often
