There are plenty of arguments that a single pipe can make as much power as duals due to scavenging effects. I run duals but the fitment was tough and I am not really happy with the clearance by the front tcase yoke. Use what fits. I used a speedway universal 2 1/2" weld up kit. I think I will just have a shop bend one up next time it was a pain to make all the cuts and weld it up. Sounds good though.
