Motad Nexxus...Power Increase?

[nikkb]

hey, i'm having a motad nexxus fitted to my kawasaki gpz500s today as the stock down pipes have blown in about 3 places
it's the 2-1 system, i was just wondering if anyone knew what difference this new exhaust system would make?
will there be much of a power increase? i understand it will be lighter but that wont make much difference...
and will it sound cooler than the stock one? lol
thanks alot

It's a direct replacement for the original. You will not notice any significant difference in power. The sound will be altered a little, but not much.

On a technical note. When you fit the exhaust, it comes pretty close to the belly pan on the right hand side. Close enough to melt it. The thing to do is to put maybe three washers between the belly pan and the bottom right mounting bracket to make it stand-off a few mm.

If it is still too close, you will find it is fairly easy to bend both the lower bellypan brakets slightly to one side (they are quite flimsy). Doesn't need much, just enough to have an air gap of 10mm or so between the pipe and the plastic.

I fitted a 4 to 1 onto my Divvy recently and it cured the monster roar from the holes in the old system along with smoothing out the mid-range power delivery somewhat.

Not much but definitely noticable.

Also, fitting after market exhausts supposedly makes a bike run leaner, so you might need to adjust the fuel mix a bit to compensate (if the power feels off...)

I fitted a Motad Nexxus to my GPZ in 2005, and it seemed to smooth out the flat spot alittle, and also made it run slightly leaner too I think.

Though it sounded nicer and was alot lighter than the twin originals.
