hey guys, I just posted up about the zorst ive just brought, its a mild steel xforce single 3 inch with 3 inch dump and 4 inch cat with stainless mufflers. Now I know everyone says about getting a tune when changing dump or cat but ive spoken to a couple of tuners and they said that it will be better than stock without a custom tune, but obviously better if I got the tune but I dont have $1500+ sitting around. Now my question is can anybody with actual experience tell me if I should be ok? just because on forums and stuff you have people who think they know what theyre talking about when they actually dont. Cheers fellas.
