GPR exhausts for the Superduke

Found this:

I've heard they were on the "cheap" side,,,,,,get another set of Yoshi's and put some can sliders on em ,,just in case,,,

GPR is a cheap exhaust, both looks and built quality. They tend to copy the design of the competition and use a lower finish.
I'd never buy them for that reason.

There are some sound files of the GPR exhaust on you tube.
Check it out.

Get a pair of Mivv Suonos and take out the baffles

I had them on mine as I was on a budget, they are ok but the paint on the end caps flaked. The UK importer did offer to replace them but I sold them on when I bought my rc8 anyway. Also the fitting was a little rudimental.

After all that though they did give a small gain in power and sounded good at half the price of the Akros
