NO, we have used several of their models all of which had interference issues, we have designed a long tube set for the First gen and they are in production now. for the Second Gen we opted to do a 3/4 length header the cars floor sits so low that a full length header would have hung down almost 2" below the frame rail. this way a 3" 45 deg bend will mate up to the collector and will be about flush with the frame rail when finished.
Ultimate Headers is building them, they use 321 material and have some nice cast elbows and flanges,
