Okay, so I fitted the exhaust last night. The bolt that holds it to the rear subframe was too short so I had to temporarily remove a couple of the spacers that hold it in place. Not exactly ideal, but will suffice until I get a longer bolt.
With the baffle in it sounds a bit girthier than standard, nothing rude and would pass scrutineering at the races. With it it sound seven more meaty. The 1m flame that rips out of the exhaust on decel means it definately needs re-jetting though.
I’ll run with the baffle in at the weekend to save BBQ’ing any of the boys behind me in the single track!!
