I'm planning to put long tubes on my maggied GT within the next couple of months. I've gone catless on a previous car and hated the smell, so I definitely want cats in the system in one way or another. However, I've read numerous threads about cats failing on FI cars, including ones in the kooks connection pipes, with the general recommendation being to use 100 CPSI cats for FI. Does anyone have any recommendations for a weld in cat to use? Would a 100 CPSI cat reduce the smell significantly versus catless?
