Well im to a point where i need to weld, yet i dont know how to weld and im stuck with a loud *** b16, so i decided to just take off my cat where it doesnt line up and clamp it, I searched at exhaust clamps and sorts allthough im not sure what kind of pipe to get or what kind of clamps i should use , i figured on the back end of the cat i could just slide a slighty smalled pipe inside of there and clamp it somehow. another thing is how do i get that pipe to connect on the front end of the down pipe. im pretty sure they sell the little bracket that connects to the spring bolt, im not sure where they sell it at.

Any help is well appreciated
