GTM Stage 2 Supercharger Preliminary Testing Results

fstrnldr

Still confused why someone would go through the time to make a long tube head but not make it equal length.

Anyway since when is it GTMs responsibility to test their products for compatibility against other non OE manufacturers offerings? Maybe they didn't feel like spending the money and time to see if a part that offers them no income from sales fits w/ their kit. Maybe there is something that can't be seen in those pictures. Or maybe it is a heat issue. The fact that the OE piece is two layer steel + a heat shield (keeping more radiated heat inside the pipe) vs the aftermarket piece which is single wall tubing with no coatings or heat shields could play a big factor.
