grottyohann y-pipe??? My 99 SS has GRot longtubes and the GRot y-pipe but the y-pipe final rusted and broke. Does anyone make a bolt-in y-pipe for the GRott headers? Rapid Motorsports flanged my headers and my y-pipe a couple years ago; therefore, the new y-pipe will have to be flanged once I get it. I have been told that Mufflex's and QTP's LS1 y-pipes are based on the Grott design but I don't know if that's true; what do you all think?
are yours 1 7/8? 
I was under the impression that QTP took over the design from Grot. My 99 donor car came with a set of grot 1-7/8" headers. They were nice looking as far as flow and fit. You could always get some mandrel bends and whip up your own y-pipe. I just did that and it wasnt too hard.
