So I've had an exhaust leak passenger side for some time now. I currently have JBA shortys on the car now. As I suspected the weld is broke all the way around the back port. I pulled the motor and trans because I'm doing a lot of work to the car right now. So my question is..... Should I weld the JBA or put the stock manifolds back on? I'll be buying kooks next year so they'll be coming out anyway. I guess with the car being supercharged I'm unsure of how much they really help. So would putting the stock manifolds back on even make a difference?
