Since I rarely have 2 “orders” at the same time, I wanted to separate myself from the one again. It’s best with an HJS. That would cost a lot more than the variant in exchange, but it also means that the buyer is allowed to keep his original cat and that this one is not broken up. Remember that the original Kat 1600 € costs at Honda and that you can also get a good sale of a used HJS….Of course only if you still have nen originalen still…beim Autoverkauf e.g. The variant with custom own construction trouser tube is of course billger, but I have to bear in mind that I can not build a 2 chamber trouser tube. Unfortunately, with original scrumpts this does not work at all, since the Honda pipe is unbeatable. For all the nen 4-1 scrumpts it would be interesting. So that’s for about 1 year the first and only original Kat that I have bought for useful money. Of course I will enrich myself, but I think the advantage is not worth it.
