I was at the DUB show in san bernadino and anyways i talked to dc they already have the tie bar out for are cars if you didn't know and i got to see thare Titanium rear sway bar that will be out in about a month for are cars and it will be around 285 dollars they said. Headers will be aout in 2-3 weeks by them also 4-2-1 they will no longer make 4-1 because it dosn't make as much power.
