As I was having my Autoform wing installed (see GTS, RT/10 Discussions) I also had the RandomTech high-end metallic substrate cats installed. I ordered these from JonB at Partsrack and they arrived two days later. I went with the more expensive Metallic cats rather than the ceramic ones because I was primarily concerned with heat reduction. Previously, sitting in traffic, the cats had burned my side sill paint black in places and heat was a real problem in my car.
The car now is *vastly* improved. There is a sort of bass thump in the exhaust note that was not there before; loud but not unpleasant at all. Also, after sitting in traffic for a while the side sills are about as warm as towells out of the drier - no problem holding a bare leg against them at all. In addition, the interior is cooler and there seems to be more power (which I need to confirm at the dyno). Anyway, I've heard people talking about the benefits of doing the cats but now I really appreciate what they were saying - this is a highly recommended modification.
As a side note, I also had the side-sill fix done while my car is in the shop. Several buzzes and rattles that were caused by stripped sill screws are now gone, and if you're having cats installed then I'd do this as well.
Cheers,
A.
