It looks like some company branded these in the US. Some clips are on the posting. I still haven't installed mine. It's been 90 fricken degrees on the weekends still.
It sounds good when warm, but the cold startup sounds awful.
@a c i d.f l y how has the exhaust and the valve controller held up? Do you have any pics of the tips on the car? Does it use the OEM controller? Thanks for any input!
