Removed the mufflers and header pipes so I could remove the flapper valve and found the other pipe was as just as bad so I also removed the balance pipe. The flapper was a prick to remove the rest was fairly easy. I used 316 s/s

and stainless in the mig it welded up easy...Result looks a lot cleaner and sounds f-king amazing.....

Pics as ( if I can get it to work )
