Marving Exhaust for KZ750E?

Webmoto.com price quote for a Marving Racing 4:1 is $420 USD delivered.

Question:

Anyone ever order from Webmoto.com from the USA and if so, how was the service?

Feedback on the Marving Race 4:1? How loud?

Webmoto states the header is special order. Any idea how long it takes Marving to make up one?

Any better alternates? I don't mind V&H, but not crazy about how low they hang. Kerker is too expensive from what I've seen ($500+). Don't want a MAC.

Im in europe and Ive ordered a few things from Wemoto with no problems.Nice people to deal with and pretty quick delivery. Havent looked at Marving but Delevic looks interesting or if youre into homemade,have a look at;

Also Norman Hyde is doing replica Harris exhausts in black chrome ,

which look very tasty.
