Finished up my long tube install today. I went from stock manifolds and lethal off road H, to Kooks 1-7/8s long tubes with catted X. Idk if its the cats or needing a revised tune but the car does not feel as strong down low. Kinda wanna get the off road sections of the mid pipe from kooks if they will sell it to me. That and the fact that now the steering wheel has play in it when it didn't before. I was reading it may be because the bolts on the knuckle were installed backwards so I will look at them tomorrow
