I have heard that a couple of people have welded flanges (3 bolt) to these headers before/after install in order to avoid the band clamp. Where did you get these flanges from?

Are extensions needed for the oxygen sensors?

For those who did duals with the summit universal x-pipe kit, how did you support / hang the exhaust? any pics? Anybody use cats?

 

extensions arent needed.............just buy some wire and solder the ends together, DONT MIX THE WIRES THOUGH. however extensions are cleaner and nicer, but if you are a good soldier then u can make it look good. (i.e.--soldier and heat wrap)
