jb weld?

 

I agree hairspray works wonders

I used 2 t-bolt clamps on both side of the coupler on the LICP... I had a long coupler so I was able to and I have those suckers so tight im surprised it didn't dent the pipe in! haha

Good Luck

 

if you dont have the pipes rolled, you can weld a lip on it and it works perfect.. thats what i do on my drag car.. and never have pop out,

 

Hit it with the hair spray and then put it together that always works for me 40+psi and holding
