The SVT and non-SVT y-pipe assemblies are different, but the only difference is the exit pipe from the cat. The SVT has a 2.25" pipe back to the flange, whereas everything else has a 2" pipe.

Ray McNairy observed this first-hand when he purchased an SVT cat in case his "mystery" mod didn't pass CA emissions.
