Skippy, Is it the stock Aussie WR426 stainless pipe you modified ?. My stock pipe on the WR426 2001 has a 1" tube that runs a fair way into the exhaust. Does this long 1" inch tube come out by just cutting the outer end plate or are you talking about another pipe. How does it sound ?. Some people punch a hole in the baffle plate at the end of the 1" tube and it sounds like crap. Chucky P.S. Where do you live in NSW, I live on the Central Coast near Gosford.
