guys the bad news is that the pits have not been made for nearly 15 years now. In my opinion they were the best flowing, best sounding, best looking 2.5 inch muffs ever made for these cars. Their straight through design with 2.5 in 2.5 out was just a perfect combination. I first purchased them for one of my gnx,s back in 1994 and put them on nearly every car I touched. When I first offered the gnx system I purchased 2 pallets of pits which was enough for 100 cars. I sold them rather quickly and when I reordered around 2000 they had changed the internal design. Originally they had what they called "power slots" in the early design. When ATR was purchased they changed the internal design to a perforated tube. They did not flow as good and did not sound as good as the original design but they were still the best thing that was available. I think the guy that purchased ATR and ruined them was also responsible for this change. I looked everywhere to find a suitable replacement muffler for the GNX systems that I was selling and all I found were compromised in one way or another. Fortunately i saved a few of the original pit muffs and I would not let them go for anything!!! The pipes system is a good system and in most respects is the best thing now available. Unfortunately it will not fit a GNX.
