Where do i get some quality couplers from?

 

seeing as no one pointed this out this is not an upper and lower kit, its an upper and an intake pipe. false ebay add.

yes a pipe is a pipe but if it cant hold the boost then you are sol. if the couplers hold and that pipe fails you will have a lot more to worry about.

I installed this.

its not up to my standards but its still a good pipe.

just remember that you get what you paid for off ebay and bootleg part from china have no traceable manufacture.
