I just dropped $1600 on an Akra Evo exhaust for my 10 with these guys and apparently got shorted in the hardware department. Numerous e-mails to their customer support have resulted in ......nothing.......nada....as in zero response. I would actually have more respect for them if they told me they weren't going to support the sale and I would have to go to Akrapovic for any help. At least then I would know where I stood.
