Not hearing the greatest of stuff about the LV on the Gas Gas, but I have a full system on my TE610 and it made a huge boost. Different bike I know, but the quality is very good.
How was the noise level after cutting it down? I'd like to chop a couple of my silencers down, but have been nervous about noise & don't want to buy a replacement.You can take a kg off of the q just chop it in half like I did!
