What's the difference between the bent header on the 2087 and the normal one on the 2045? I've got a used Fire 11 on the way and too many pipes to choose from(2058, 2087, 053, 2063, SH "High Torque", and the engine is coming with a 2045 with non-RB header, whatever that means..) I also have a long NR header laying around. Just thinking out loud, from the videos I've seen of the 2045 it looks to rev pretty well, so maybe the long NR header on the 2045(long header for more torque, and the F11 revs well anyway..)?

The engine is going in my SC8, which I'm planning to bash around with... If it runs well it'll be a backup truggy race engine..
