I'm looking at putting the O.S. .18 TZ (P) engine into a Kyosho V-One RRR.

I am unsure which exhaust combo will work let alone work well. I'm going for a balance between torque and fuel consumption.

These are what appear to be my choices.....

A) O.S. T-2050SC Mark Pavidis Tuned Pipe With Manifold (Welded Nipple)
B) O.S. T-2060SC WN One Piece Tuned Pipe With Manifold (Welded Nipple)
C) RB Concept Polished Exhaust Manifold .15-.18 (Revo/On-Road) made just for the OS .18 TZ engine- With unknown pipe

???

Thanks!

EDIT: Nevermind, I just realized the to O.S. exhausts I listed above are 180 degree manifolds and I need a 90 degree. Looks like the RB manifold is it.

Any suggestions on a good pipe for it? How about the Novarossi EFRA 3005 One Piece Tuned Pipe (No Manifold)?
