looking to fit an aftermarket pipe to my 1125r. quite like the look of the Jardine RT5, will i have to get a power commander aswell or are there fuel maps to suit this exhaust

Check out the exhaust thread at the top of the tech section before you spend any money.

Make sure you avoid the Remus. When their (crap) welds fail, they'll only be interested in selling you replacement

Fek all goodwill

Get an albert666 can, the noise is fantastic and they are a work of art.

I have a RT-5 on my 1125CR, it sounds the business and has not fell off/apart etc. I actually found it made the bike behave better at lower rpms and have not had to tinker with the fuelling, I have got the latest flash and noticed very little change in the bikes behaviour. $250 gets you one of THESE from uncle Erik if you really want to get it spot on.......
