need help with installing fabspeed bypass pipes

[ChrisZang]

Hi,

so my Christmas gift to myself was a set of fabspeed bypass pipes which I picked up NEW at an incredible low price at eBay

So, they came today and as the wifey is shopping and I have nothing better to do, I tried to install them - but no luck.
I know that a few of you have installed the successfully, so I hope I can get a few pointers

a) I can't get the end of the pipe properly aligned with the "U-pipe" which leads into the muffler. It seems to me that I need to saw approx 3/4" off the pipe.
I wonder if anyone else had a similar problem?

b) the pipes come in two parts: the long bended pipe which connects to the primary cat and a second short pipe which fits very loosely onto the first pipe. Question: do I simply stick it on and mount it (I am afraid that this will rattle a lot) or is there a clamp missing?

Needless to say: the pipes came w/o instructions...

Thanks & Merry Christmas
Chris
