I have the Profab one, looks like they've been long gone for a while.No idea... Not gonna be a guinea pig on stuff like that. TBTH... none of those tubular ones are gonna be good for much besides massive clearance for intercooler piping and weight savings for a drag car. Street car... MM is really the only one I would (and am) trust besides the stocker now that the Steeda is DOA. Again... Maybe the BMR will be ok when they get their shit together...
