Hello, sorry too hear they are no good, as you say Bummer.

I did a similar thing a few years ago and as it was sometime before I attempted to fit this, silencer, as it was about 2 years it was not an option to take it back, it looked OK but on offering it up the flange from silencer to pipe was different being from an earlier model, not much different but enough and because of it being chromed wasn't really abled to be altered without making a pigs ear out of it.

We live and learn or sometimes even, why don't I learn, so now I check everything as it arrives.

Cheers D.
