Wow that's awesome. When I started reading this thread I was thinking what Alex was. I am really, really surprised. Makes me wonder what my catless + Hush system would test at... not that I wanna find out the hard way

Does anyone have the papers from HKS that say the hi-power catback is legal? I called them and asked them to fax it to me, but I don't have the receipt so they wouldn't send it to me. I just want to have these in my glove box in case I ever get pulled over.

 

no but even though u get a copy, they'll most likely have an emblem (embedded, dunno the right word to say) or something that u can't really photocopy very well. I have an official Greddy Evo certificate, and it has an emblem "embedded" onto the paper.

 

HKS usually faxes them out to people, so I don't think it is embossed. They only guarantee their exhausts will stay legal for 13 months, so its possible that they date the papers...hence the reason they won't give it to me w/o a receipt.

 

I just got a Hks Hi-Power and I love it. It's kinda loud but sounds sick. I'm interested in the papers too.
