os rg is great for the money.
also do not forget the pipe for it.
this is a list of pipes i have tried on the rg in order of preformance.
1. fioroni ot ma03 best all around for me
2. os t2050 (best fuel mileage real close all around to the fioroni)
3. power racing 086 (the rb 9886 is supposed to be better)
4. jammin jp1
5. ths tourqe
all the pipes worked well but the fioroni was the smoothest and had the most top end at least for me.
