Hi Guys

Not too sure about this but I got a FMF fatboy expansion chamber and muffler. Is it safe to just throw on or should I wait till I recon the bike?? I'm going to get my cyclinder replated when I do it unless total moto x come up with a shit hot price on a new one.

Also would I need to rejet the bike with the new pipe, some say no bolt on and use, others say new pipe - more power - but to get more power, got to use more gas. Is this right????

Cheers

Stephen
