Salut, c'est deux tubes inox soudés sur les coudes d'origines. J'avais mis deux dbkiller pour atténuer un peu le son mais c'est non homologué malheureusement.
I love these orange stripes! I plan to built 535 this year and I wanted to go for orange color but now I need to rethink my vision as these strips are really dope! Also I would love to hear the story behind bottles that you have on both sides. Looks neat as well! Hope you still have and enjoy this bike!
