torchredgt Posted March 13, 2008 Report Share Posted March 13, 2008 I am thinking of getting Steeda UDP's on my SGT. My friend got them on his 04 Mach 1 and said they are like night and day. Has anybody installed them or know anything about them. The claim to ad 10rwhp, is this mod worth it? Will I need a retune? Any drawbacks?? Thanks in advance.
