Does anyone know the company Götz? (exhaust etc.)

Moinsen! After my neighbour changed my machine and I can now make a lot over winter, the exhaust question arises. So far my little one has decorated a nice BOS Titan pot. This should now be replaced with a nice Leo Vince (Titan), but by chance I just came across the following page:www.goetz-motorsport.de which also have a nice titanium pot for quite little $ in the offer:KLICK ME Does one of you know the brand/the company? as? According to such a local mopped book, the super processed, very light, have “downside” more performance than other manufacturers and bla… are just classified as very good… I don’t want to spark an exhaust discussion here, just get opinions about the manufacturer… nice holiday you (I hope you have better weather than I just do…) edit: stupid smilie in the 2nd link…just look at the article number: 3326767…
