LT's, Catted-Y pipe.....CATBACK?
So i just ordered american racing long tubes and a catted Y pipe for my 1998 Z-28. I previously ordered a magnaflow cat back exhaust (dual Tips). However the gentlemen on the phone said i would need to add an additional part to tie in my y pipe to my catback as they are different sizes? Anyone have any input on this. I was assuming that these would all be direct fit bolt on parts. Are there catback exhausts that will fit the Y pipe? Or am i going to have the same issue wherever i go? Any input on who has done this, or dealt with this in the past would be great!
Thanks,
Derek

I know that the american racing headers y pipe is 3". I bought the more expensive version of the Magnaflow (which has the dual tips) for my cat back system.
It didnt make sense to me either. That is why i am asking the question. i assumed that the cat back and the y pipe were the same size?

ok, so what do i need to do to make it work or will it work as a bolt on scenario? Do all catbacks come like this? If not should i have ordered a catback that does not neck down to 2.75" at the connection and stays 3" throughout?
Thanks in advance.

I think the ARH Y-pipe is 3" throughout. It sounds like the magnaflow cat back pipe that ties into the Y-pipe necks down to 2.75". I am not sure why this is done, and am hoping someone could answer. I posted the same topic in the ls1/ls6 external questions thread hoping i can get a response there.
