installing Che Boxster Test Pipes

[vitaminC]

Has anyone installed the pipes available from delubozparts ( http://986forum.com/forums/273505-post1.html)?

I am following the basic outline described by Maxspeed, and it seems like the small section of pipe that goes between the test-pipe and the muffler's u-pipe is way too loose. Only one clamp per side is shipped with these pipes, and it doesn't seem like the original double-clamp will slide over the pipes.

Any thoughts?

This is going onto an '03 S with an otherwise stock system.
