I know the classic look is for two pipes, but I kinda like the 2 into 1 look for an exhaust. Is there a "performance" reason for one over the other, or is there no real difference?
2007 fatboy is the bike in question, I'm from oz, dont know if there's any spec difference betwwen ours and american models....
Will the bike "learn" the new exhaust or do I have to sort the tuning out???
The 2-1 broaden the power band of the motor (the torque is better) because the pipes help scavagen each other removing all the exhaust residue for the next blowdown event. 'Yes' the 2-1 is better for performance and 'yes'you will have to tune the bike for them.
