These are very well made pipes that givr the car a deeper sound, mostly from outside the car.
According to Alex, I have an early version of these on my 957 Turbo S and am wondering if you could send me a a pair of the hanger brackets I could weld on to support them correctly. If so, PM me and I'll send my address or just look me up in the Fabspeed system from my prior purchases.

Hi Scott, same situation here (older version installed on my car with no supports on them.) Are supports available for purchase or would you recommend that I have an exhaust shop install some? Thanks, Joel
