GREAT!!!
I absolutely love this exhaust! It’s a high-quality full system that delivers incredible sound. It’s very loud without the baffles, but adding a power commander and the appropriate map really enhances the motorcycle’s performance. There’s also an optional silencer available, which can tone it down a bit while still maintaining that awesome low grunt sound in either configuration.

Loud and fun
The install was fairly straight-forward. I had no idea so it took me a bit of time but if you know what you're doing then I think you could have it installed in 15 minutes. It is so much louder than the stock pipe. It brings a smile to my face though and people like to stare. You can really sense the increase in power too, it seems easier to red-line in 1-2 and I think the bike revs lower at 60Kph than before so it should provide a higher top speed. Fast delivery to Australia so thanks for that. I have two Brock's exhausts now (the other on my Ninja H2) and I would highly recommend them.

Love it.
Not only looks and sounds great; it is very well build, with good quality components. The most important thing is that I get a kick out how it makes my little Z sound like a big bike.
