Tru Bendz catless y-pipe good investment??

[spoolinmonkey]

I have a 99 contour svt as some of you may already know and i have a few questions about tru bendz y-pipes. I currently have a cheap ebay cai , resonator-delete, no cat, and flo-pro mufflers (crappy) :with i had wish i had magnaflow! Anyway i found a set on ebay for $240with for without a cat, and the price isnt the problem, i want to know how much of a bit$# these are to put on, and if there are any potential side effects if i put these on.
-are there any sensors or computer issues that would come up?
-will it mate with my stock piping?
And i will have my local muffler man put them on how much could this cost?
Lastly will i notice any difference in performance or at the very least sound???
....thanx alot guys
