TSP ORY not matching up to cat back So i installed my headers and y-pipe the other day, went to throw back on the LM2 cat back..and the end of the y-pipe seems to be a 2 1/2" were as the start of my cat back is a 3...the y came with 6 3" clamps..so a pipe being 2 1/2" doesnt seem to make much sense..anyone else run into this problem?

I had the same issue when I went to install my LM1. The merge on the end of the Y is designed for the stock size catback, being 2.75"
My thread shows what mods I did to the Y when I did my MagnaMouth

The end of my TSP y didn't match up right either to my i pipe. I had to do a little fabricating to get it to work. Which is often the case when putting together a bunch of different aftermarket parts.
