Dude, that's not professional at all. From what I know, professionals dont like clamps. I did my own exhaust setup, if you see my pics, it looks ghetto as ****e, but I did it and I am not a pro . . . or maybe I am . . . hummm . . . I can start my own shop.

 

i was thinking the same about clamps...you should have that whole set up done right
