Welcome to the forum and congrats on the bike bro.
Mods are great, once you get started they are addicting. Go through the "Do-it-yourself" threads and find all the stuff previous people have done. The search option is very confusing but it's getting modified for easier clearification.
Hopefully one of the guys can link you to a thread that has a great overview for new members.
Good luck and ask as many questions that you have.
p..s. The Jardin is probably one of the loudest pipes but you loose major torque/power and the maintenance and quality sucks!!!
