One of Kerry's M8s (steve I think) has a 4into1 system and had been setup on a dyno for max power, he also runs 010s and chases down well riden Gixer 1000's but he's a bit of a nutter though.wesexcellence said:On that topic. Will my fjr respond just as well without the cat?
What are the pros/cons besides the obvious?
I know I need a power commander but do I also need to have it tested?
Can you use a power commander with the cats?
