it does need a dual setup but the fmf muffler im running has pretty much no restriction. I know air in air out creates horepower

i just need to figure what dual setup to run gibson is supposed to be sending me a less restrictive muffler they are working on i allready have the header which is bigger than the stock. Not sure if this wiil really help

For me my biggest gain was the Intake I went with the K&N set up by removing the whole air box similar to a cold air intake and proper jetting. I do have a Gibson to stay quiet. I noticed the most bottom end with a better intake. Even over the Sheve CDI duners kit and exhaust. I think we are all looking for more power without spending a ton of money. Let us know when you find the answer.

did the 686 kit w/10:1 compression piston, stage II cam, port & polish. did'nt notice the increase i was hoping for. a friend suggested new carb /w intake & exhaust, made all the difference in the world, very impressed now.
