Hi All, I've been looking at getting an aftermarket muffler for my z750 as I'm thinking its a bit quiet for my tastes. I was doing a bit of research and found that you can actually have your existing factory muffler modified. Has anybody gone down this route? I'm not really chasing extra performance just a bit more noise and a better sound. At the moment it just sounds like whizzing sewing machine. My little zeal had a better note ffs! Just wanting to know if anybody has regretted not just going with the aftermarket cans available. At the moment I'm leaning towards a LeoVince GP Pro but if my muffler modified can acheive the same sound or similar I'd be happy.
