Pros and cons again, I agree with Adam and Fourbolt for different reasons, mainly the material does make a difference, due to expansion rates mainly, as the RB is thicker it doesn't expand as much and is a bit stronger against dents and such. But With the Mod carried out the the manifold of the OFNA, it is a far more responsive pipe than the RB for less bux, but you will be bending it back into shap more often (if you do it while it's still warm it's better). So IMO balancing out the 2 sides and taking price into consideration, I would go for the OFNA, But if you go to www.microtechracing.com and look at the pipes section then there are some nice RD Logics jobies that just whoop the ass off of both of them. I run all 3 pipes in question on various buggies and find the RD to be the best and surprisingly cheapest.
