I've heard aloads about this and spoke with akrapovic. They are a big deal in motorbike circles
Ive also seen first hand their Audi and Porker exhausts. The Ti welds are v good, up there with Amuse but not necessarly better. Their Ti blend mix is different to the Japanese Nippon steel stuff. There is alot of attention to detail in their logo and X's which tbh give no gains. They also include a CD fitting manual, gasket glue and loads paper work. But you pay for it. will be circa £4,000 + vat / $7,000
its nice they use a dyno, unlike some jap brands. It won't be a big seller as so much competition in JDM, will be for guys who want something rare and unique.
