Exhaust ideas 4 RB20

Recommended Posts

I have a modified rb20. 32 tm mikuni, 62mm crank, case weld and transfers opened up all the way on the cylinder.  Picture is the kind of work done, but not mine. I currently have a jl mk4. It's the full race. I'm not a huge fan. Although the power kicks in like a turbo it has very little torque down low. I am looking for an exhaust that will give me torque down low but will allow the motor to rev high. There are many choices and I am a bit overwhelmed.  Any thoughts, experience is helpful. 

Chiselspeed CST 4, CST 6, or cst 8

Rayspeed nk 

Franspeed sport tourer

Pipedesign  charger or Voyager 


Or is the answer a variable ignition?
