tru tru learned this w/ a " A/C CAOMPATABLE" downpipe. went to install it wasnt compatable at all had to cut and reweld that bitch. it wasnt compatable AT ALL

if your trying to stay w/ a budget just get a unversal kit w/ various bends, clamps and couplers. get them mocked up and indexed and i can have them welded at a decent price wether they are aluminum or steal just lmk
