is dented so for this weekend i have several choices in exhaust to replace it.
I am looking for torque. Wich exhaust is the best choice;
capricorn 2662 with RB manifold (came with the 2604)
nova 2601 with medium NR manifold
CRF 2647 with CRF manifold
I have the RB 2659 now but its lacking grunt.
Or a combination, maybe?
Regards
I would go for the Capricorn pipe out of what you have. The best pipe for the RBM3 is the RB2668. I have not tried the CRF.
