I'm on the fence, Ignition vs. Exhaust... Exhaust I'm leaning toward a CHM, not sure if I'll go with the P4R or the SM1, seems like the SM1 is the way to go b/c others here claim no loss in bottom to the stock system and excellent power mid to top with great transition. Otherwise, I'm considering a JD Ignition fro Pro Circuit. My question is, which is better for performance, Ignition or Exhaust System? My buddy has a PC T4 slip on and it made some difference in bottom end but mostly just made some noise... I ride tight tracks and wide open tracks both, sandy and hardpack so what do you think? I'm surprised more people DO NOT have ignitions, that seems like a great way to add power!!
