As seen earlier in the thread, I run an open wastegate vent pipe (or Screamer as some call it).
Obviously it has transpired that there may be noise issues with certain venues forthcoming, so in a mad panic I got on the phone yesterday and ordered this little lot......
.....and set about making this......
Just hope I have done enough!!
It's interchangable with a non-silenced pipe for those times when I want to go for the Subaru-style 'look at me' approach.
