Ray good to see its a goer, after changing the jets tomorrow if still not much difference open up the end of the can to at least 35/38mm or in your imperial talk 1 1/2 inches through the baffle so you carn,t find it ever again and put in one of lars,s mesh inserts that he makes for pro duo mufflers but they allso after looking tonight at mine that I am now fitting to the blue bike that GPR oval muffler I believe you have one too it looks like the mesh insert will go straight in, there, 1 inch or 25mm hole just aint big enough it slowed my now 800 yellow bike down.
Or just take the baffle out and go for a small ride with ear plugs and see what happens , you may gain that bottom end and mid range power where we ride most of the time.
Just for a tempory thing you could get some mesh stuff and snip and fold it arround the end of the tail pipe of the muffler and hold it with a radiator clamp to give it a tad of back preasure and keeps the cop.s away while testing .
