Finding the same thing. My euro wholesale supplers carry HUCO. Made in India, which puts me on edge. But the 'Bufkin' pipe is being replace and plant to spend a lot of time at high RPM's in two weeks.
I went ahead with the Huco brand. Have yet to install... Read some about them on the Volvo and Saab forums, seems to be a solid performer over there.
That Bufkin pipe is a very nice piece.
Then again, there is eBay if you want the Bosch unit....
